HI Elaine,
I am on 500 mg of seroquel a day to help with sleep it also helped with the fleashback frequencey which made ever side effect worth it for me. I at first was scared as well but after the drug is in your system, it gets way easier the side effects lessen and life goes on . I at first was really tired and felt really out of control when they started the seroquel it made me feel " goofy" too for a while but after a while it became leveled out in my system, and it has helped so much so in my opinion you should be cautious but it has done wonders for me to the point I can work again. Good luck what ever you pick
