You can do it! I used to DREAD the weekends. And they are hard at first.
Make plans, to do lists, keep busy. Come here if you get stressed. If you are where people are drinking, make sure you have a get away plan. You don't want to get stuck somewhere.
I stayed home a lot and drank tons of hot tea.
AA helped too, but I was too chicken to go to a meeting for 6 months...don't be chicken, everyone there understands just what you are going through.
Looking forward to hearing how it goes!
