I sympathize about the weight gain. But it's better than the extreme insomnia I had w/out seroquel. And if anyone tells you seroquel does Not cause weight gain---get this. I was on it for about 6 months. Gained around 35 lbs. (added to the 30 I gained on Depakote). I was about to go on vacation for 3 weeks. My MD was on vacation. Her Physician's Asst. told me "Stop taking all your meds while you're on vacation so you can lose weight."
I did, thinking she knew what she was talking about. Yes, I lost 20 lbs. in 19 days! And that was with eating TONS---full Scottish breakfasts, giant lunches, big dinners, snacks.
But I was crazy. After Day 3, no sleep at all. Talking a blue streak. Wrote 45 letters to a friend in the first 10 days. Seeing things, manic laughter, etc. etc.
Got home, called MD said "I did lost 20 lbs. but I went crazy going off the meds." She said "Why on earth did you go off your meds!" I told her the PA told me to. She was furious, said that was out of order. She made the PA apologize to me. I gained those 20 lbs. back within 2 weeks of going back on seroquel. I hate the weight gain but prefer being sane.
