most times 1/2 seroquel works wonders nightly for stopping the racing thoughts and gives me 8 great hours of sleep; however, there are a few times when i am so stressed that 1/2 seroquel does nothing and even though i keep a regular bedtime, 5 hrs. later i'm still awake. do any of you combine some other rx or over-the counter sleep aid or anti anxiety med to finally knock you out. not sleeping really trashes me for an entire day following and i try to catch up with several naps. i don't get on computer, drink coffee, etc. and have 2 noise machines and a completely dark bedroom, all to no avail at certain times. any suggestions?
