Thanks everyone for your replies. Day two and I'm already feeling up a notch.
Sleep is a big issue of mine, and always has been. But then it's hard to separate it out from the drinking. It's great to hear from those who say it's tough for a while, but you adjust. Can't wait until I can actually just have a normal night again.
On the other hand, maybe I'll get a lot of reading in while I have the hours to spare at night.
Thanks again.
