seroquel u mean? it does cause drowsiness which is very prominent in the beginning when u take it, but after your body adjusts to it the symptom is not as severe. 50mg is good to start.
seroquel has two type, one is short release and one is extended release. the 25mg only comes in short release. it's a small round tablets. the extended one lowest dose is 50mg and the tablet is capsule type (long and not round). I am always on extended release
