I was on Lorazapam through chemo for nerves and to help me sleep. It worked... but I felt all messed up the next day and when i didn't take it at night, it was even harder to sleep than before. It took me a while before I was able to sleep without it and I didn't take it that much in the first place. Mostly just through my surgeries because I was in pain and that kept me up at night. I had to just cut myself off when the pain stopped and not take it regardless how difficult it was too sleep. Once it was out of my system I was fine. I've heard that's one of the risk of taking it for sleep. I don't know for sure, but might be worth looking into.
