Quetiapine
"This is the only med that actually helps me sleep. I had tried melatonin, zopiclone, lorazepam and temazepam, as well as every natural remedy I could get my hands on and then my doctor suggested quetiapine. I take 25mg about an hour before going to sleep and usually by the time I climb into bed I can hardly keep my eyes open. I'm also taking bupropion (which is technically contraindicated with quetiapine) which may be why I feel so sedated on such a low dose. The only downside is that I don't fully wake up from it until I've been physically awake for at least an hour and it makes me really thirsty. But that's a small price to pay for getting a good sleep after struggling for years. Also it makes orgasms less intense for me which sucks!"
