It was like watching someone else do it, but I couldn't stop.
For twenty years, celebrated children's author Sally Gardner spent compulsively and catastrophically, losing more than £500,000 before understanding that the medication prescribed to quiet her restless legs had quietly rewritten the rules of her mind. Dopamine agonist drugs, long known to trigger impulse control disorders in Parkinson's patients, carry no equivalent warnings for the women who predominantly take them for Restless Legs Syndrome — a regulatory blind spot that has left hundreds of patients financially ruined, relationally broken, and psychologically adrift before anyone thought to ask whether their behaviour was a side effect rather than a character flaw. In the space between a prescription and a warning never given, entire lives were quietly dismantled.
- Sally Gardner lost over £500,000 to compulsive shopping she couldn't name or stop — buying the same shoes five times, ten dog beds, rooms full of unwanted things — while everyone around her mistook pathology for prosperity.
- Hundreds of patients on dopamine agonist drugs experienced similar devastation: broken marriages, lost homes, criminal behaviour, and suicides, with compulsive shopping hiding longest because it carries no public shame and leaves no visible wreckage until the accounts run dry.
- A stark gender gap sits at the heart of the crisis — UK guidelines require doctors to warn Parkinson's patients, who are mostly men, about impulsive behaviour risks, but no such obligation exists for Restless Legs Syndrome patients, who are mostly women.
- Neuropsychiatrists note that online shopping is uniquely invisible as a compulsion — there is no moment of social consequence, no feedback loop to trigger alarm — allowing the behaviour to masquerade as extravagance for months or years.
- The UK drug regulator has opened a review of dopamine agonist warnings following a BBC investigation, while Sally Gardner remains on the medication that harmed her because it is still the only thing that lets her sleep.
Sally Gardner's literary success arrived like a flood after decades of struggle — 2.5 million books sold, prizes won, real money for the first time. Her friends watched her spend lavishly and assumed it was the natural excess of a writer finally arrived. What none of them knew, and what Sally herself wouldn't understand for twenty years, was that she was trapped in a compulsion she couldn't name.
Around the same time her career ignited, her doctor prescribed dopamine agonist drugs for Restless Legs Syndrome — a condition that made it impossible to sit still, sleep, or rest. The medication worked. Her symptoms vanished. No one mentioned psychiatric side effects. But the shopping intensified into something unrecognisable: the same shoes purchased five times, ten dog beds for one small terrier, rooms filled with things she didn't want. She lied to friends, hid purchases, felt ashamed. She described it as a drumbeat — each buy delivering a dopamine hit she immediately needed to chase again. She sold her north London townhouse to cover her debts, then spent tens of thousands on an interior designer for the smaller flat she moved into. Her friends began walking into local shops to beg staff not to serve her.
It took twenty years and more than £500,000 lost before she connected the medication to her behaviour. The BBC heard from hundreds of others with similar stories — debts, broken relationships, homelessness, suicide. Compulsive shopping went undetected longest because it carries no social stigma; online orders arrive quietly, and excess can look, from the outside, like generosity.
The drugs are prescribed for Parkinson's disease, Restless Legs Syndrome, and other conditions. Their link to impulse control disorders is well-documented — but the warnings are not applied equally. UK guidelines require doctors to discuss behavioural risks with Parkinson's patients, who are predominantly male. No equivalent requirement exists for Restless Legs Syndrome patients, who are predominantly female. Sally was never warned and never monitored. A doctor noticed something was wrong only once, when she arrived at an appointment carrying shopping bags.
Professor Valerie Voon of Cambridge notes that compulsive shopping is as common a side effect as gambling or hypersexuality, but remains hidden far longer. There is no public moment of consequence, no social feedback to signal that something has gone wrong.
Sally has reduced her dosage since learning the truth, but she remains on the drugs — they are still the only treatment that works. Every purchase now demands a moment of self-interrogation. The UK regulator is reviewing warnings following the BBC's investigation. For Sally and hundreds of others, the gap between what was disclosed and what actually happened has left a mark that no review can fully undo.
Sally Gardner's life changed the moment her first children's book found an audience. After decades of struggle, her career suddenly took off—2.5 million copies sold, major literary prizes, real money for the first time. Her friends watched her spend lavishly: a £3,000 bathtub, prints by Peter Blake, shopping trips to Paris. It seemed like the natural excess of a newly successful writer. What they didn't know, and what Sally herself wouldn't understand for twenty years, was that she was caught in a compulsion she couldn't name or stop.
Around the same time her literary career ignited, her doctor prescribed dopamine agonist drugs to treat Restless Legs Syndrome, a condition that had plagued her for years. The syndrome meant constant, unbearable urges to move—she couldn't sit through dinner, couldn't watch television, couldn't sleep. She was newly divorced, raising young children, navigating menopause, and chronically exhausted. When the medication worked, it felt like salvation. Her symptoms vanished. No one mentioned psychiatric side effects. She felt euphoric.
But something else was happening. The shopping intensified into something uncontrollable. She bought the same pair of shoes five times. She purchased ten separate dog beds for her Yorkshire Terrier. She filled rooms with things she didn't want and didn't need. She lied to friends about her purchases, denied wearing new clothes, felt ashamed of the money pouring out of her accounts. She described it as a "drumbeat" of compulsive behaviour—each purchase delivered a dopamine hit, and she chased that feeling again and again. By the time she recognized the pattern, she had amassed devastating debts. She sold her north London townhouse and moved into a smaller flat. Even then, the compulsion didn't stop. She spent tens of thousands on an interior designer. Her friends were so alarmed they began walking into shops in her neighborhood, begging staff not to sell her anything.
It took her twenty years and a loss of more than £500,000 to connect the medication to her behaviour. She had thought she was going mad. Hundreds of other patients experienced something similar—the BBC heard from families who didn't make the connection until it was too late. There were stories of massive debts, broken relationships, criminality, and suicide. Some couples lost their homes. Most of the cases involved compulsive sexual urges, but shopping addiction was common too, and it went undetected longer because it carried less social stigma than other impulsive behaviours. When you're ordering online, there's no immediate feedback, no moment of public shame. Friends and family might interpret it as generosity rather than pathology.
The drugs in question—dopamine agonists—are prescribed for Restless Legs Syndrome, Parkinson's disease, pituitary tumours, and some mental health conditions. They work by boosting dopamine activity in the brain. The problem is well-documented in medical literature, but the warnings differ sharply depending on who receives them. Doctors are required by UK guidelines to discuss impulsive behaviour risks with Parkinson's patients at review appointments. Parkinson's patients are disproportionately male. There are no such guidelines for Restless Legs Syndrome patients, who are mostly women. Sally was never warned. She was never monitored for side effects. A doctor questioned her behaviour only once—when she arrived at an appointment laden with shopping bags.
Valerie Voon, a professor of neuropsychiatry at Cambridge, explains that compulsive shopping is roughly as common a side effect as compulsive gambling or sexual urges, but it remains hidden longer. "When you're online shopping, you don't get feedback very quickly," she says. "You can just order multiple things online and not be that conscious of what you're doing." There's no social stigma attached, no moment of public consequence. The behaviour can continue for months or years before anyone notices it's pathological rather than simply extravagant.
Sally published an erotic novel under a pseudonym while on the medication—something she now questions whether she would have written otherwise. She has reduced her dosage since learning the truth, but she remains on the drugs because they're the only treatment that works for her Restless Legs Syndrome. She will live with the financial consequences for the rest of her life. Every purchase now requires a moment of self-interrogation: Is this compulsive? Am I doing it again? The UK drug regulator is reviewing warnings for dopamine agonist drugs following the BBC investigation. Manufacturers say the warnings are clearly stated and the drugs have improved many patients' lives. But for Sally and hundreds of others, the gap between what was disclosed and what actually happened has left a permanent mark.

It's another health scandal where women are sidelined. We weren't warned. We weren't monitored.— Sally Gardner

La Conversación del Hearth Otra perspectiva de la historia
When you first started spending like this, did you feel it was a choice?
No. That's what's so strange about it. I felt ashamed, but I couldn't stop. It was like watching someone else do it. I'd lie about what I'd bought. I'd deny wearing new clothes. But I couldn't stop.
And no one—not your doctor, not anyone—connected it to the medication?
Not until I heard the podcast, twenty years later. My doctor prescribed the drug, it worked for my legs, and that was it. No monitoring. No warnings about behaviour. One doctor once saw me with shopping bags and questioned it, but that was all.
Why do you think it took so long for this to be recognized as a side effect?
Because it's shopping. It's not as visible as gambling or sexual behaviour. You can order things online and no one sees it happening. Friends think you're just generous or successful. There's no immediate social feedback telling you something's wrong.
The guidelines require warnings for Parkinson's patients but not for Restless Legs Syndrome patients. What's the difference?
Parkinson's patients are mostly men. RLS patients are mostly women. That's the difference. It's another health scandal where women are sidelined. We weren't warned. We weren't monitored. The consequences were the same, but the care was different.
Do you still take the medication?
Yes. It's the only thing that works for my legs. But now I battle with the compulsion every single day. With everything I buy, I have to ask myself: Is this compulsive? Am I doing it again? I'll live with what I lost for the rest of my life.
What would have changed if you'd been warned from the beginning?
Everything. I would have known what was happening. I would have been monitored. I might have made different choices about the medication, or at least understood what was happening to me. Instead, I thought I was going mad.
