"where do i begin? seroquel, personally i think it is a great medication for the right person. i&#039;ve taken seroquel on and off 3 different times, i am currently back on it and will most likely stay on it. i take 800mg before bed time and sleep like a baby. i do have a few side effects from this medicine which include dry mouth, constipation and indigestion. i take seroquel for borderline personality disorder (bpd), i am also on 300mg lithium and 300mg 3x a day of gabapentin. seroquel helps control my mania and impulsive behavior, it does not make me a zombie and i have great concentration. what i don&#039;t understand is this drug being prescribed to people for sleep issues, sure you sleep like a baby but those are the people with all these terrible side effects and horror stories."
