insomnia
"I have been taking Quetiapine 50mg every night for almost four years for mainly insomnia and bipolar episodes. This drug makes me fall asleep within 90 minutes of taking it. It took about 6 months to finally figure out when the best time for me to take it was. I recommend having the same bed time every night for best nights sleep with this drug.

When I first started taking quetiapine, I had mild hallucinations as I got drowsy Little things like the wall `tingling` have been seen. After over 3 years of taking this medication, my muscles have started twitching randomly. Each month it is getting slightly worse. My doctor and I are thinking of switching to another drug. 

Overall this is a great medication for insomnia, not for long term use."
