It does sound like your lithium level might be a bit high. Those are all symptoms that you get when it is high. You must eat a substantial meal before taking lithium and don't drink too much liquid when you do. If you take it on an empty stomach it can make you feel a kind of sick you don't ever want to feel. Call your doctor and tell him what's going on.

I've taken seroquel and never had any of the symptoms you describe. The timing that it happens at the same time everyday is curious. What else is going on then, what are you doing?
