Your story sounds remarkably similar, I tried to start a thread in the newcomers section but it wouldn't let me for some reason the page just goes white.
Anyway I'm 5 weeks sober and have settled pretty well into sober life, I just got back from a restaurant after watching my mates get pissed, make idiots of themselves and then drink drive home. I really didn't feel like I was missing out on much at all!
I wouldn't have believed I would be in this position a few months ago but it really wasn't as scary or as bigger deal as I built it up to be. The best piece of advice I can give is to give up when you truly decide that you've had enough, that's what I did and I found it so much easier when I 100% believed I was not going to drink, it was hard but I just got on with it because I didn't have a choice my decision was final.
Good luck and let us know how you get on!
