Hypnotherapy.
It is important that you do not focus on trying not to drink. It doesn't work very well and can have the opposite effect like this. Stop smoking.
You see, you imagines a lit cigarette didn't you. Whereas before, you were not thinking about it, the thought has popped into your head. If you are a smoker then your just about to light up a cigarette in the next 5 minutes.
Instead focus on your addictive behaviour, recognise the patterns of the addiction and how we submit to them. Then you will be able to break the addiction patterns and therefore avoid occurrences when relapses occur.
