Murray & Joe, Thanks for the information. I have read everything I could find on it and believe me, I don't have an alien limb, just one stubborn leg who decided it wasn't ready to get in the car yet!!!! Have had no problem since, and neither did I have a problem with it before. So it must have been as I suspected. Overly tired, stressed, and in need of Sinemet. As Ever, Marjorie 67/12
