"i was prescribed 75mg of seroquel for insomnia. it worked like a charm, for about the first week. then it made me sleep too much. i was sleeping 12-14 hours a day and was still waking up groggy. as well as gaining around 25 pounds in a matter of 2 months my physician and i both decided that it would be better to stop taking it. but i still will keep the rest of the medicine i have just in case there are one of those nights that i can absolutely not sleep. great medicine, just not for me."
