I used to suffer from compulsions and developed a related trick to break their grip that normal willpower just couldn't provide. Sufferers will be familiar with the 'you must do X, otherwise Y might happen' state (where X is often something pointless and Y is something 'bad' - dying or similar). I found a way to extend that thought with '.. or, actually, if I do do X, Y WILL happen' - hence the best move became not to play. Now years on, this habit seems to have proven enough for my brain to 'snap out' of a compulsion and eliminate the majority of their negative impact.
