...if not more devastating than PD, what would you do?

after taking sinemet cr and using requip over 7 years, dx 11 years ago, the medications side effects cumulate to a stage that they are sometimes more damaging than PD:

when my dosages of sinemet exceeds 1000mg per day, i will have severe withdrawal dystonia, so i keep it below that level

taking sinemet at too close intervals will give me extreme drowsiness and speech disorder - kind of overactivated vocal muscle which makes my word unhearable. thus a longer spread of intake intervals is required.

overall undermedication lead to frequent balance loss and tendency to fall...

any suggestions?
