Trazodone
"Couldn't sleep. Dr prescribed 50mg and 10 minutes after taking this medicine I felt extreme anxiety and felt panic .  Heart racing.  Looked it up immediately and saw it was a side effect with some people. But  it is not scarier than not sleeping.  Will tell Dr next time I go in what happened. Now just up when I can't sleep and hoping there is something that will help. I tried ambien which worked for a while but had an episode of sleep walking on it. I don't know what else there is to try.  Did all the natural otc stuff and exercised more but I still wake up in the middle of the night and can't fall asleep again.
