Hi, I have just started taking the new style Sinemet Plus tablets, made by MSD, had my first ones yesterday am. I am very achey especially round jaw and shoulders, and have a nasty high pitched tinnitus. This is a little complicated because I am not fully recovered from a fluey bug. Nevertheless, I do not seem to be getting the same effect from these as the old version. What are your experience? Has anyone else had difficulties? Or felt a difference ?
