I was on 600 mg of Seroquel after I went through a trauma & the nightmares kept me from sleeping. I had lost an extreme amount of weight also. I was so hung over & useless during that time but I definitely slept. I would liik into other meds if it's just sleep that you are being given it for. That is a heavy med just to take for sleep unless you have a definite reason for not being able to sleep & only need it for a rather short period of time.

I quit taking it when the nightmares ended though I still have had a few now & then but living alone in the middle of the country after leaving my H, I couldnt afford to be knocked out like that or hungover living alone.

Hope you can find a better solution for sleep
