Alternatives to Seroquel for Sleep

I take Unisom and Melatonin extended release in doses of 10mg or 20 mg, as directed by my doctor. That mostly works on a daily basis, but when it doesn't work I add diazepam to that. For major needs for sleep I am prescribed amitriptyline and it works! Too good. I have to take the lowest dose and that really leaves me in a deep sleep. That is my go to when I can't sleep whatsoever. I have a problem staying asleep. I've tried ambien, lunesta and others but they don't keep me asleep. Just sharing my own experience.

Thanks quietgirl. I’m going to ask my doctor about amitryptaline.

When I was recovering in the hospital for a couple of months staring at the white ceiling tiles, they put me on Melatonin.
A hospital is active 24/7, there is always beeping noises and the feeding/breathing tubes turned me into a mouth-breather. My mouth was always dry.
I really didn't notice any help sleeping from the Melatonin as they woke me up every 4 hours to take my vitals, administer meds, draw blood & reposition me, etc.

I couldn't wait to lie in my own bed at home with my cat again. I would dream of looking at white ceiling tiles.
My mild sleep apnea got much worse (82 events per hour avg) and after discharge, I was given a CPAP machine. I trained myself to be a nose-breather again. Now I find it hard to sleep without the CPAP.
I am grateful for the staff that saved my life. It is good to be alive. I no longer take Melatonin and not sure if it really ever did anything for me.
Some of my room-mates at the hospital worked for a large local company that handed out Melatonin like candy when they had an upcoming 'fireman shift' or trans-oceanic flight for business.
It made me realize that I was pretty lucky not to have a job that put my obligations to them over my health.
