Hi the good news is you are only 20 years old. So take your time and never go cold turkey. You'll need to change to the regular seroquel. (Don't know what the dosage equivalent is - maybe your psychiatrist does.) Then you can begin with a small decrease in dose (very small) - reach stabilization, park awhile - then small cut in dose again - reach stabilization, park awhile - (you get the picture) until you're off. Listen to your body, if it's uncomfortable, you're going too fast. Nobody knows your body like you do (no doctor, no one.) Eat whole foods, exercise, and enjoy being 20. Best of Luck : )
