My name is Ruth . I have had Parkinson's for about 4 years and have been on Mirapex since June 1998 now taking 1.5mg 3 x day. I have possibly been on Riluzole for 9 months. I have had no passing out but one sleep attack about 8 months ago. I was very tired at the time so there is some question that I could have naturally fallen asleep but I think not. I believe it was a sleep attack from the Mirapex but I have had no more. I am just especially careful to stay rested especially before driving and no more long trips.
