Disulfiram
"Best thing I've ever done, tried every other possible way to stop & this is the only thing that has broken my nine year daily drinking habit, I couldn't recommend it highly enough to anyone out there that just can't stop. I take it at night as it makes me drowsy but suits me as it now serves as a sleeping pill as well, a bit dizzy & nauseous in morning but early days. I take 1/2 tablet - 50mg every second night"
