Why do I get so nauseated? I'm also getting muscle twitches. I'll have to talk to my psych doc about it. I hate feeling sick so often. I don't know if it's got anything to do with my meds or not. Why wouldn't I feel nauseated all the time if it were my meds? The twitching I think is because of meds. Will tell my doc and see what he says. I don't know if I should worry about it or not.
