"hi all! i&#039;m diagnosed with ptsd and bipolar type 1. after my most recent manic episode i crashed into the worst depression and extreme anxiety i&#039;ve ever experienced. i was tried on the usual antipsychotics and had dangerous side effects from all of them except seroquel. for years and years i&#039;ve had extreme insomnia. i was started on seroquel (300mg) for sleep about 6 months and it was immediately effective. i love being able to sleep, but i&#039;m sleeping 10  hours. i&#039;d like to try to cut back a little and see if i can get to 8-9 hrs/night. my psychiatrist tells me i&#039;m not just taking it for sleep, but for the bipolar itself. i&#039;m still not back to my usual self due to lack of interest in anything. hopefully i&#039;ll soon be better!"
