The problem may be gastric emptying, that is, the medication stays in the stomach for a long while, developing gas while it is there along with other ingested material. Sinemet in the tummy does nothing for PD. It has to get into the small intestine to be absorbed. Solution to the 'no response' may be in the timing of doseage. Take Sinemet a while before meals with liquid...maybe a Coke. This may make one feel 'burpy' for a few minutes but the gas will disappear and the Sinemet should work. It's worth a try.
