I read in a posting on this forum advice that we should avoid taking Sinemet. Why? How is it harmful?

I do take Sinemet, and my complaint is that while it allows me to move faster and, along with Amantadine, takes away my tremor, it also makes me clench my teeth. I am afraid that this clenching will have a negative effect on my teeth. Also, surprisingly, my handwriting suffers when I am ON Sinemet.

I would appreciate some input on Sinemet and how if affected you.
