Linda,
My daughter takes seroquil for bi polar. It does make her tired, but it really helps with the mood swings. Maybe if he gets on the right kind of med and the right doses he'll see improvement. They started her out on too much seroquil so she cut it back and feels just right with it now. Still a little sleepy but better.
You should be proud of yourself for staying out of it, I know how hard that is to do.
Take care, hugs.........Lo
