I've never experienced the not being able to breath thing, but I get a wicked bad case of restless legs and general restlessness with Seroquel. Doc gives me Ativan for it, but I have to take so much it makes me dopey the next day. I should probably just take it all earlier in the evening instead of waiting for the last minute.
I take Lamictal so don't have any experience with the other meds. Good luck.
