I started taking a couple different diphenhydramines and they just left me drowsy, and nauseous after i woke up. So i stopped taking them. Even after a few sleep cycles i still felt drowsy after sleeping without taking anything. I had been taking prescription pills for sleep [seroquel] but they just me nauseous till the drug wore off. Initially i was taking clonapin [sic] for sleep,but the doctor changed it for a reason. the unisom & other sleep aid i was taking also caused me to feel me depressed.
