Welcome KP. So you drank last night? Day 1 is never easy, so go easy on yourself. If you can muster up the strength to do something healthy for yourself (a short walk? A chore around the house?) you should, it will keep your mind off drinking.
You can do this, stick around SR. I did, and I'm 71 days sober today. I'm still recovering and healing from my past, but 71 days ago I woke up the morning after and literally wanted to die. I thought I was helpless and hopeless. It feels so foreign to me now and I'm so glad it passed. It can improve for you if you just don't drink.
