i've taken Seroquel for several years - it is an anti psychotic - not sure why drs use it for sleep. was on 300mg which i reduced down to 100, but i don't sleep well, talked to dr she increased back to 300mg which i tried but was very drugged next day, so i'm back to 100, which i will start cutting. i want to try natural melatonin. has any one tried any natural treatment?
