The night time is the worse for me also. I usually watch a movie to distract me although I am losing interest in that also. Do you keep a journal? That helps a little but only while you are writing in it. Truth is losing control of something is very nerve racking, but you have to find a way to keep your mind from wondering. Our imagination is usually much worse than reality I try to remember that my W is hurting just like me although I believe the WAS hides it better than we do.
Get up real early and make sure your day is really busy so when night time comes your tired and just want sleep. I've been taking over the counter sleep aids but they are worthless to me. I threw them out this morning because they don't work at all. Just stay busy and keep your thoughts in check.
