Not drinking for 30 days! Seeking advice, encouragement and stories.

I tried for the first time to stop drinking last week and made it until Saturday, 5 days. I ended up going to a birthday party on Saturday night and although I went in trying not to drink I ended up having several beers. I didn't get black out drunk I let myself and my girlfriend down.

My girlfriend has backed me 100% but has had too much and she needs some time. We are taking the week off. If I cant do this not only will I end up ruining my life but also will destroy my relationship of 3 years.

I don't have a lot of hobbies and am looking for good things to do instead of drink, especially on the weekends. Friends and family all drink a lot so I don't even know who I can talk to or spend time with. Also looking for some advice and personal stories to hopefully help the second time the charm.

tl;dr Tried to stop drinking for 30 days, made it 5 days and relapsed. Looking for help before I ruin relationship and life.
