"i have taken this medication in the past for insomnia and i admit it works great. if i take 25mg i&#039;ll go out and fast but it doesn&#039;t keep me asleep so i have to take 50mg or even more for it to last. i stopped taking it due to the weight gain, i read about it and seroquel causes your blood sugar to drop which is the reason for the hunger - and the reason i only wanted cereal. that&#039;s the reason i stopped taking it but i am considering asking my doctor for it again because since stopping i have tried so many different sleep aids and nothing works. from trazadone to ambien to now sonata - and nothing works so then i end up taking like 3 pills which i know cannot be good."
