I used to take trazodone, but that didn't do squat. I still have over a half bottle sitting around somewhere. Right now I don't take anything for sleep, though most of what I do take has drowsiness as a side effect. My body got used to it, so I just fall asleep whenever I can. My screwed-up back "helps" with that, too.
Everything I currently take I can't do without, at least until I lose some more weight. I've already lost 40lbs since December, but I still have a ways to go. Getting there, slowly, but surely.
I wish I did have some recommendations for you, but sadly, I don't. I hope you find something soon that'll work for you.
