i had been on serequel two or three different times. i took it the past year. but i stopped i had near fainting and dizzy spells. i could not climb a ladder. now im just on 4mg of risperdal. my car felt like it was just all over the road on serequel. turns out my car is just as wide as a lane of traffic. i had to wait until 2pm to drive everyday. i would be careful mixing serequel with antihistimines. i accidentally messed up my vitals signs taking serequel with an antihistimine. the antihistimine was prescribed for me to replace serequel . i just needed better sleep hygiene. for seven days i was supposed to take a quarter of the serequel with the antihistimine. i messed up and forgot and took a whole serequel by mistake. i had bad vital signs and had to call ambulance.
