the first one, Carbadopa, helped initially, and then not. Now I am on
Mirapex, and again, it helped initially and now it is not, even though the dosage(s) were increased.
You may want to schedule and appointment with a neurologist, just to get a check; make sure you look into what other symptoms (sx's) you may be experiencing, even if they seem unrelated.
Good luck and keep us posted!
