Blackfeather,

I agree with soccertese, talk to your neuro.

I would expect 100mg of C/L to get a response. Possible reasons for it not to include:
- the drug's not being absorbed, for instance you're taking the drug close to eating protein or you're constipated;
- you don't have PD;
- your assessment of whether or not it has an effect doesn't have enough resolution, for instance you may have a mild case of PD, with your body's endogenous supplies and reservoirs being almost adequate.

I'd stick with the 100mg dose as prescribed by your doctor. With this dose I'd run a test using the side to side tap test:

Parkinson's Disease Measurement: PwP, surveys, trials, analysis

The first few times that you do this test you learn how to get better results. So, do the test at least 10 times or until the results stabilize, and throw away the results. Then, starting a hour before the dose, do the test every 15 minutes until 3 hours after the dose. To avoid confusion, you should not eat before or during the test, except that you should eat a biscuit and drink some water with the dose (this is to ensure gastric emptying). Draw a graph of the results. A response (a higher number of taps) should be obvious.
