I am so sorry you are having difficulties. I am not up late, my Phy Dr. has me on a med to help me sleep, because I have trouble going, and staying asleep. I still have the same problems, but I do get some sleep now. I usually have nightmares, wake 4-5 times a night, and would only get a couple hours a night. Now I get a few more hours of sleep, and only wake2-3 times now, but I still have the nightmares. I also catch my self thinking like you do, but once that med kicks in I am out, but it does take 2-3 hours for that med to kick in. My thoughts, hope, and prayers are sent your way, and hopefully you won't have that problem tonight.
