Acamprosate
alcohol dependence
"Chronic binger for  37 years. Cramps and diarrhoea for a week. Neither anywhere near as bad as after 5 or 6 litres of vodka. For the first time in my adult life I don't want a drink as opposed to wanting not to drink. Difference is the complete absence of underlying anxiety. It's gone. Feels as if I have joined up thinking again. I think I'll keep taking the tablets."
