Thank you so much to everyone, your replies really mean a lot to me.
To answer a couple of questions I havent tried any suppliments etc, as I honestly havent been really serious about quitting before. It came and went as a passing thought that I shouldnt be drinking so much, but this is the first time Ive really decided I need to stop. I havent tried AA and I honestly dont think it would be right for me.
I resisted the temptation to get some drinks tonight, as its Friday night here in Australia and Im usually great at justifying getting drunk today. Very small step but its a start.
Thanks again,
Dan.
