I read the DATAPOP study results for the Eldepryl trials and was not impressed. The study indicated that, if helpful, eldepryl provided 9 months delay in the need to begin sinemet. Given the cost of eldepryl and its marginal benefit and side effects, I decided not to take it. Incidentally, I tried eldepryl for 2 weeks and had terrible head aches from it. Gray (50/3)
