insomnia
"I have bipolar 1 disorder and though I manage my condition with lithium, I have trouble getting to sleep at night which leads me to insomnia which ultimately leads  to manic episodes. I take between 12.5-25 mg a night of the seroquel and it works within about 45 minutes or an hour. It puts me right to sleep. It's the only medication that has ever consistently worked on putting me to sleep. I feel a little bit groggy in the morning sometimes if I take 25 mg. Also it increases my appetite at night. I've probably put on a little bit of weight because of my snacking but it's so worth it to me."
