I have been suffering from Parkinson's disease for about 4 years. My first treatment was Sinemet, but now I am taking Requip. Both these treatments work well in controlling the situation, but both produce most unpleasant sensations in my mouth. I would like to know of any way of alleviating this. At times it seems to me that the cure is worse than the disease, so unpleasant are these sensations. Margaret.
