Dad just started taking the Mirapex today. He took one before I left (I had to take my niece back to the Pittsburgh airport for her return flight to San Francisco, then I returned to my own home), and I don't know for sure, but I think it may have made him sleepy. It's hard to tell though, since he usually takes a nap in the afternoon anyway! A note to Sid Roberts- Dad and Mom are both planning on attending the next Parkinson's meeting. Would you please speak with Dad about your experiences with Mirapex? I know both Mom and Dad would certainly appreciate it, as would I. I have been sending him all of the letters I can on the initial effects. Thanks! Trish
