as other have said, it's probably the Mirapex. But many years ago, before my husband was on Mirapex, he also blacked out with Sinemet. He has passed out in more recent times while driving with Mirapex. Hence, he does not drive any longer. However, dehydration has been a factor too. ---------------------------------------------------------------------- To sign-off Parkinsn send a message to: mailto:[log in to unmask] In the body of the message put: signoff parkinsn
