I was diagnosed with Parkinson’s about 1999, over twenty years ago. Progression was slow and after finding the right drug dose Sinemet 25/100, it worked well, but had to recently take what my doctors considered the maximum of 8 pills a day. Then my doc retired and left me in the hands of a fairly young doctor who wanted me to either decrease it to 6 a day or try Rytary. So when I could not reduce to six, I opted to try Rytary, which worked for 6 months when dyskinesia occurs. Thinking of going back to Sinemet. Rather deal with every 2 hours than dyskinesia.
