as others have said,be totally honest with your doctor.i used booze to sleep too,among other things,when i looked at myself when i got sober and how it was with me and booze, i actually found that i used booze for everything,it was my solution to life.things are beyond words now,i never imagined i could feel like this.i go to AA partovme,and found a much more preferable solution to life there.if i can be of any help to you at all please feel free to pm me if you want to chat.
..ps,im just up in scotland,from york origionally!
