Stay busy, stay hydrated, and for me, I'd stay away from bars. I've done the same thing in the past, gone out before I was probably ready and even though I may not have drank the first or second time, eventually I wore down and had a drink. I believe that you are strong enough to handle it, but it seems an unnecessary risk this early on.
I like to have a to-do list ready for the weekend, of some chores, errands and fun stuff I want to do. It kind of keeps me on track and doesn't let me have any down time except the down time I WANT to have, where I sit and catch up on the shows I like or do my nails or something like that
Maybe you could have a list of things you'd like to do this weekend ready?
