I just saw on TV a commercial for the drug Mirapex which is a medication for restless leg syndrom (RLS). The warning for it reads:
MIRAPEX may cause you to fall asleep without any warning, even while doing normal daily activities such as driving. When taking MIRAPEX hallucinations may occur and sometimes you may feel dizzy, sweaty or nauseated upon standing up. The most common side effects in clinical trials for RLS were nausea, headache, and tiredness. You should talk with your doctor if you experience these problems.
Right at the end of the commercial came the added warning of: "You should also consult a doctor if you experience increased gambling, compulsive eating, or increased sexual urges." What?!?
