By Rethink Drink. For UK adults. Reviewed November 2026.
The talk people mean when they search "Claudia Christian TED talk" is called How I overcame alcoholism. She gave it at TEDxLondonBusinessSchool, in London, in 2016.
You can find it on YouTube by searching its full title: "How I overcame alcoholism | Claudia Christian | TEDxLondonBusinessSchool".
In it, the actor best known as Commander Susan Ivanova in Babylon 5 talks openly about her drinking, the many things she tried, close to 20 relapses, and how she came across The Sinclair Method, which uses a medicine called naltrexone.
For a lot of people, her story was the first time they'd heard the word naltrexone.
Matt, our co-founder, was one of them. He found Claudia Christian through YouTube autoplay. In his words: "And for the first time, someone was talking to me logically; about the brain, not morality."
Whether a medicine is right for you is a decision for a prescriber who knows your health.
In short
The talk: "How I overcame alcoholism", Claudia Christian, TEDxLondonBusinessSchool, 2016.
What she covers: how her drinking changed over the years, quitting cold turkey, rehab, therapy, AA meetings, prayer, close to 20 relapses... and finding The Sinclair Method.
The big idea in it: the alcohol deprivation effect, the craving that can build after a spell without a drink.
Her story is hers. It shows what happened for one person. Controlled trials show naltrexone has a real, modest effect, and results vary.
In the UK, naltrexone is licensed to help people stay stopped. Using it The Sinclair Method way, before drinking, is off-label.
Check first: if your body depends on alcohol, stopping or cutting down too fast can be dangerous. Speak to your GP (General Practitioner) or local alcohol service before you change anything...
Who is Claudia Christian?
Claudia Christian is an American actor, best known for playing Commander Susan Ivanova in the science fiction series Babylon 5.
She has written about her drinking in her 2012 memoir, Babylon Confidential. In 2013 she set up a non-profit, the C Three Foundation, to raise awareness of The Sinclair Method. And in 2014 she produced and narrated a documentary about it, One Little Pill (Wikipedia and Wikipedia summarise all three).
What does Claudia Christian say in her TED talk?
She starts by explaining that it crept up on her.
In her own words, she was a very light drinker in her twenties and a social drinker in her thirties. In her early forties, she developed alcohol use disorder.
"I was always the last person standing at the bar or at dinner parties."
Then she talks about trying to stop.
She quit cold turkey. She went to rehab. She had talk therapy for over two and a half years. She saw a hypnotherapist and went to 12 AA meetings in two countries. She changed how she ate. She prayed.
And she relapsed. "I probably relapsed close to 20 times. And each relapse became more difficult to recover from."
If that sounds familiar... you're in good company. On calls, people often tell us they've tried everything. AA, rehab, detox, apps, coaches. Some of it more than once.
She's clear that it wasn't about a bad upbringing or weak character: "I wasn't drinking because I had a crummy childhood." And she describes the moment she realised she wasn't in the driver's seat any more.
"Addiction is a monster, and it affects every ethnicity, social class, race, sex, age; it doesn't matter."
From there, the talk moves on to how she came across naltrexone and The Sinclair Method, and why she now campaigns for more people to know about it.
What is the alcohol deprivation effect she talks about?
It's the part of the talk that lands hardest with a lot of people.
She describes what can happen after a spell of not drinking. The early relief wears off. The craving builds. "You drive by a liquor store, and you're triggered, you want a drink."
If you've ever been sober for weeks or months, had one drink because there was an occasion, and found yourself straight back where you left off... that's the pattern she's describing.
It's not a willpower problem. Stopping for months takes a LOT of willpower.
Willpower is the wrong weapon in this battle.
We explain the alcohol deprivation effect, where the idea comes from, and how far it applies to people, in The alcohol deprivation effect. And if a slip after a long break is where you are right now: Alcohol relapse.
What does the research say about naltrexone?
One person's story, however powerful, isn't evidence for anyone else. So here's the research, in plain words.
The big review. A Cochrane review of 50 trials, with 7,793 people, found naltrexone lowered the risk of heavy drinking to 83% of the risk on a dummy pill. On average, one in nine people was helped. A real effect. A modest one. Those trials used naltrexone in different ways, not only The Sinclair Method's way.
Support made the difference. In a Finnish trial of 121 people who were still drinking, naltrexone helped people who also had coping-skills sessions: 27% never went back to heavy drinking over 32 weeks, against 3% on a dummy pill. With general support only, it did no better than the dummy pill (Heinälä and colleagues, 2001).
The 78% figure. You'll hear it in talks and documentaries about The Sinclair Method. It comes from Dr Sinclair's review of his own clinics in Finland: 115 of the 147 people who completed enough treatment to be classed were counted as successful. Open treatment, no comparison group. Not a controlled trial. We break it down honestly here: The Sinclair Method's 78% figure.
How does The Sinclair Method work, in plain words?
When you drink, your brain releases endorphins, its own feel-good chemicals, in its reward areas. Brain scans have shown this happening in people (Mitchell and colleagues, 2012). The endorphins land on opioid receptors, and that's the reward.
Naltrexone blocks those receptors, so the endorphins have almost nowhere to land, which is how the reward cycle is interrupted.
Taken before drinking, at a time your prescriber sets, the reward isn't there. Over time, the brain stops showing up for a reward that never comes... a bit like a job you're not paid for any more. For many people, the desire quietens and drinking comes down. Or stops, if they choose to.
It's not the medication itself that makes the method, it's the protocol of how to take it.
The full explainer: What is The Sinclair Method?
Why did her talk matter so much?
Because she said out loud what a lot of people felt and couldn't say.
That she'd tried everything. That she wasn't weak. That relapse after relapse doesn't make you a bad person.
And she talked about the brain, not about morals.
For many people, that changes the question. Not "what's wrong with me?" but "what's happening in my brain, and what can help?"
What should I take from it?
Hope, and a starting point. Not an instruction manual.
A few honest things to hold alongside it:
A talk can't assess you. Naltrexone isn't suitable for everyone. Its UK patient leaflet says not to take it with severe liver or kidney problems, or if you're taking opioid-containing medicines, including some painkillers. A prescriber needs to check.
The UK picture is different. On the NHS, naltrexone is usually used after you've stopped, to help you stay stopped. The Sinclair Method is off-label in the UK, so many GPs won't prescribe it that way. Can I get naltrexone from my GP?
Please don't buy it online without a prescription. Here's what to check: Where do I buy naltrexone in the UK?
The tablet isn't the whole story. A medicine can quieten the desire over time. But it can't change our habits. The Friday nights, the stress, the routines built around a drink over years? That's the real work, and it's why support matters so much.
