Re: scared to try seroquel...
Ugh, not being able to sleep well IS miserable. Sorry you're having this trouble. What aspect of trying this med frightens you? Have you tried it yet? Your doc thought it a good one to try to relieve your symptoms, so it seems that if you can get past the initial panic over taking another new med, giving it a fair try would be worthwhile. If it works, great! If not, you'll know, and you can move on, and it wouldn't likely be any worse than now.
I'm sure there are lots of others here on the board who could speak from more experience w/ seroquel... You can always do an advanced search here for any other threads discussing it. There's a wealth of information here.
