To sleep good for a loooong time I take a couple of 3 mg melatonins, two 25 mg benedryl tabs and one Doxylamine (Walgreens Wal-Som) but can wake up kinda foggy so sometimes I only take 1 ben and 1/2 a Dox. They don't really make me fall asleep quicker, just knock me out for longer without waking up after only a few hours.
