I believe both can cause it. There may be a difference in the way people fall asleep as Joe so well points out. I haven't read the literature specifically about it. I am talking about from personal experience with both Mirapex and Requip. As Linda noted the most important thing is not to stop driving because you are taking the meds(although if one has difficulty because ao other aspects of PD it would be a wise idea) but to be aware of the possibility and if it becomes a problem while driving or not to then consider not driving.
