Bob and Nancy, and Carol, Too much Tasmar PER DOSE might be part of the reason for the return of the dyskinesias that Carol is experiencing. I have VERY good success with Tasmar by cutting the 100 mg pills in half, and only taking the resultant 50 mg no more frequently than once every four to six hours. My total daily intake of Tasmar is about 200 mg.(4 x 50 mg). I avoid freezing up for the most part, using this SMALL DOSE amount. For freezing up or lack of motion problems, I have found both SInemet and its generic substitute to be effective, and much milder medications. If I add about 1/3 of a carbiddopa/levodopa 25/100.tablet (yellow color), every 40 minutes, I return to normal, without overdosing. Hope this may help. Ivan :-) 50/39/36
