I've been on seroquel for about 5years, ive been taking 500mg a night, it was prescribed after my doctor said i had schizo effective disorder when i was 19 years old i am now 24. And i feel my life is great execpt for one thing seroquel as it did help me to sleep, and calm me down at the time of my episode back when i was 19, now it has and is still ruining my life. I gained 50kgs which im not sure what that is in pounds probably about 105pounds-ish, i managed to drop about 25kilos but am forever gaining weight and it is a constant battle just to mantain my weight let alone lose the weight, but thats not the worst thing. I am constantly tired it doesn't matter how much i sleep i am still tired i have to go to bed at 9.30pm just so i can wake up at 8am to go to work, and i am so tired all day even after that much sleep and even if i sleep for 12,14 hours i am still tired my partner says that sleep rules my life and nothing is as important in my life than sleep, because im tired my concentration is so bad and my memory is worse, im just in another world and always out of it seroquel runs my life and i hate it im am so scared to come off it, but ive decided that im going to start to do it. and finally rid my life of, this disease which was supposed to help me but has completely taken away my hold on my life, i will not be ruled by seroquel anymore.
