I take Seroquel 150 mg. It makes me sleepy so I take it right before bedtime. At first I was so manic I still had problems with insomnia. Eventually it all worked out. In the meantime google up all the things you can do to naturally help with insomnia. I can still have problems if I am under pressure or stressed so I take 200 mg. I really feel for you as I have suffered from insomnia for years. I think part of my problem was hormonal because as we grow older our progesterone level decreases leaving us with estrogen which revs up our systems making it harder to wind down. Good luck with your situation.
