I know there are meds that supposedly help with stage 3/4 sleep or dont interfer with our sleep cycles but has anyone seen any studies involving med combinations like a benzo(which is suppose to interfer with deep sleep) and avanza/mirtazipine which can enhance deep sleep, there are lots of other combination but just wanting some actual info on this. In my case avanza by itself doesnt help me much but when i use a benzo with it like valium i do feel like i sleep better then with valium alone. I will note that i do rotate bewteen a few meds to avoid tolereance and have used combinations as well under my docs advice. cheers!!!
