You were at an extremely high dose of Seroquel, did you take
seroquel in the day as well? Definitely try spreading out the
dose. If you still having
sleep issue, you might want to try Trazadone, it's not an addictive drug, and it makes you sleep like the dead. I also sleep with a wedge pillow for reflux, but I'm told it's good for snoring too!
Some folks just have RLS which hs nothing to do with the meds you are on.
