-- [ From: Donna Kipp * EMC.Ver #2.10P ] -- Joseph , I was interested in your post concerning tyrosine. I had done some research on it a few years ago but was leery of trying it because it is an amino acid and was afraid it would interfere with my Sinemet. I assume that is not the case. How much do you take and how do you time it with your Sinemet. Donna
