Don't get me wrong, I've got anxiety issues myself, and if I'm dealing with something the next day that gets my mind racing the night before I take 0.5 Lorazpam, which is a very small dose. And nothing beats those meds. If you get your full night sleep on it you don't feel groggy. But because my job can be intense and requires a lot of thinking during the day, I somehow manage to do with out the aid because I'm just done and fall asleep at night.lol..but I wouldn't use it everyday. I use it as an absolute last resort.
Further to that, in my experience when I take those meds, I don't get a good restful deep REM sleep. I get the hours of sleep but I don't wake up feeling "wow, I feel refreshed" compared to nights of natural deep REM sleep.
