hi im seventeen. and ive been on seroquel for a couple of months now. and yes ive gained weight but most of it was from zyprexa. but im bloated from seroquel and i look a bit pregnant to tell you the truth. but what ive noticed from this drug is im experiencing EXTREME muscle stiffness in my jaw and the pain is horrible. docs dont know whats wrong so they just give me tylenol 3. but when thats gone what am i to do. cos they cant give me anymore.... and nothing over the counter works. and im still in extreme pain. hopefully the pain subsides in a few days cos tonight is the last night for the 400mgs of seroquel that im on. i heard haldol gives worse pain... true or not? let me know. does anyone know of any anti psychotic that decreases weight? other than abilify..
