haven't tried it, would be too costly for me. In reading the message boards, getting the right dosage seems to be a challenge for some patients and some give up. But keep in mind not that many people post on boards, probably best to read this document and then check with your insco and neuro if you want to try it.

just curious, see you are taking TEVA brand C/L, my pharmacy can't get it, can you check if your pharmacy can still get it? TEVA bought out ACTAVIS and i can get that brand but i like the TEVA better. If TEVA stops making generic sinemet that doesn't leave that many generic manufacturers.
