I feel your pain
I've been sober since August and still don't have a very good sleeping pattern. I tend to sleep in 3-4 hour spurts. If I can, I will slip in a nap during the daytime, which actually just makes things worse at night. My problem, among many, is that I drink too much coffee during the daytime.
Oh, well....things will get better. In the meantime, a little insomnia is a small price to pay for not having anxiety, the shakes, nervous stomach, guilt, and all the other alcohol/drug-induced problems like before.
All the best.
