"i have had a problem with sleep for a long time. my doctor prescribed seroquel 50 mg. it works great - it takes about usually and hour and fifteen minutes to make me fall asleep. i have to eat about 35 minutes after i take it because i get hungry from it. if i don&#039;t eat i won&#039;t sleep well. it&#039;s a very good medication. i do sometimes once in a while feel dizzy and feel lightheaded. other than that it&#039;s good."
