Hi, Rosebud...I wasn't able to determine whether or not you have already started the Mirapex and this "nodding off" had begun before or after taking Mirapex. I will just tell you, though, that while my pwp was taking the Mirapex, she experienced exactly what you said you have experienced....but, in all other respects, she felt really well while taking this medication...definitely alleviated...actually, eliminted her tremor...BUT, she had to stop taking Mirapex due to her developing OCD which is a side effect of this medication for some. She is now taking another medication along with the Sinemet, and this other medication (Parlodel) is in the same "family" of medications as Mirapex..very similar...but, she's taking it at a lower dose than the Mirapex. Although this medication seems to be helping with the tremor..as did the Mirapex...she definitely is experiencing the same kind of "sleep attacks" as you mentioned you are experiencing especially the sudden falling asleep experiences which is of prime concern as related to her driving....although, she has assured me that she is not experiencing the "sleepiness" when she drives. However, since it has been noted that Mirapex can cause sudden sleepiness..without warning...and since the Parlodel is a similar medication, there is some concern that she could fall asleep suddenly while driving because she certainly falls asleep very suddenly and without any warning when she is at home...I'm not certain that any of what I've said is of any value to you, but I felt that there was some similarity in what you are experiencing and what my pwp is also experiencing. I guess I just felt that I wanted to "warn" you about the Mirapex...especially if you have not already started it. If this is the case, then, it seems quite possible..even probable...that taking the Mirapex might only enhance the problem.

Take care, Rosebud...
