I was diagnosed in 1992 and have had DBS surgery. At 73, I am actually quite healthy. My question deals with protein intake due to Sinemet being blocked by animal and even quite a few plant proteins, namely amino acid foods. Are the other Parkinson drugs also sensitive to proteins? Has anyone else experienced this sensitivity and how do you overcome it? I am quite active but without the amino acid foods - lentils, nuts, soybeans, seeds - my energy suffers. Thanks for your help!
