My phsychtrist put me back on seroquel 100mg. My problem is im afraid to cintinue to take this. Ive been seeing some nad things w/it. 1st off my cousin(like my twin) passed away from heart problems the seroqeul caused. Now my girlfriend has been changed from seroquel to a diff med. She is having dizziness, fast heartrate, chest crushing, & passing out spells. I dont really trust this medication. Should i ask my phsyctrist to switch me because of my concern or what are your opinions. I have a fast heart plus the chest crushing feeling as well. Your thoughts would be appreciated. Im scarrd of this med but i have to be on something. Thanks everyone.
