Hi Acidburn, good to see you here.
I'm into day 4 and still I can't sleep. I have no clue if this is withdrawal or anxiety but I know right now I'd rather be losing sleep by trying to stay in sobriety than losing sleep due to my drinking habits.
Maybe try and see your GP and be honest with them. People here talk about withdrawal and if this is your first night in sobriety in years it might be a good idea.
Take care of you and I hope to see you back here.
Thinking about you.
