I did not use any medication to help me sleep. It was a small price to pay to get my brain and body "normal" again. I wasn't working at the time, so my days and nights were just minutes and hours....I got up if I wasn't tired, I slept when I was tired, and eventually things evened out for me.
If I were working, it may have been a different story, but seriously, I spent many nights up all night and still made it to work with that hangover; I could make it through each day one more time.
Stay strong and stay stopped. Know things will get easier in time.
