Welcome Tristy and congratulations on your decision to stop drinking!
I was scared to think about a life without alcohol, too. There was a period of adjustment, for sure, but I find that I actually enjoy my life a lot more now that I'm sober.
Only about 10% of people drink like we do, so there's plenty of people out there having fun without getting wasted. Infact, I still attend things where alcohol is served (as long as that's not the main entertainment!) - I just don't stick around for the after-party.
Getting support is so important...... Starting out here is great first step!
