insomnia
"After trying various over the counter sleep aids (Benadryl) and prescription sleep aids (Ambien, didn't work unless I used in high doses, in which case I hallucinated), Doxylamine works! I used to have to take 100 mgs/ 4 Benadryl, in addition to various prescription tranquilizers/benzodiazepines for insomnia.  Can't believe how quickly it works.  I still have to take 50 mgs in addition to a prescription tranquilizer, but after years of OTC medicines not working, I can't believe how well this one did.  Don't recommend 2 pills/50 mgs for most people.  I'm very difficult to sedate."
