Thanks all for the replies.
On the note of gratitude that often gets mentioned, I haven't really given that much thought. The main motives for me to quit drinking is that I don't want to develop liver disease, I'm sick of the hangovers and feeling rubbish, I want to improve my health & have started a workout regime, the drinking is hindering the latter. I'm seeing that the rationale is to give more to be thankful of and more 'pull' factors to help build motivation and determination.
I'll think about everything that's been said. Thanks again for the suggestions & help.
