I was on ambien 10mg and seroquel 200mg q night. I was completely knocked out for several years. I wanted to get off the Seroquel because my cholesterol went way up on it.
The ambien quit working for me. I have ativan. That quit working too. My dr said I could take 3mg of ativan and that still didn't make me sleep. It's been over a year and a half that I literally get no sleep some nights and only a few hours some nights. Never have I slept more than 2 hours at once. If I'm lucky, I'll get 5 hours of INTERRUPTED sleep a night 2x per week.
I have: magnesium glycinate, melatonin 5mg, glycine, 50 MG seroquel, hydroxyzine, clonidine, and pasionflower tincture. Each night I try a combination of 2 to 3 things. All of these are supposedly good for sleep. However, I still cannot sleep. But, hopefully you could look into trying one or all of them. Good luck!
