In reply to Seb2007:
I don't suppose it'd do any harm. You could try saving drinking for one day a week if you find you're struggling, and have an enjoyable rest day?
I don't drink by the way, but it's what i'd do I think if I found I was struggling, rather than going back to drinking over the whole week, so you'd get most of the benefits of not drinking.
