Niki,
I have not as a rule had trouble sleeping. However, in the past several weeks I have been having a lot of problem going to sleep. It's been since I have cut back on my drugs as well. It's very frustrating I hate not being able to sleep. It's not the pain that keeps me awake I just don't go back to sleep. I told my OS's nurse and she suggested several things, such as a shower in the evening, Tylenol pm or benedryl. I haven't tried benedry as I don't have any. I may try to go out today to get some. I hate it when I don't sleep at night than I am sleepy and want to sleep all day. Hopefully this is just a phase and will get better in time. It is miserable. However, it is another one of those things that we can expect according to what they say here on Bone Smart.
Good luck I hope it gets better for you real soon.
