Brian, Most of what I've read claims that Sinemet is felt almost immediately (within a few days, perhaps?). Others on the list have told me that it took them awhile to feel the benefits. My mother (Joyce, 67/5 months) started with Sinemet 25/100 3x/day (or was it 4??). She did not feel much of anything for a long time (a month or so). The doctor then slowly had her add Permax and she began to notice a change. Unfortunately, she didn't feel back to normal when on the combination, but she did notice when she needed to take the next dose. Also, some days are better than others. I would definitely bring it up with your doctor — perhaps a different combination would work better for you. Good luck and good health.
