Steve I went onto entacapone last year July and had the same thing happen, it was a revelation, and the only negative thing about it was how annoyed I was that my neuro had not done it earlier, I too feel better than I have done in years. Like you I never kicked in to the extent that I was really mobile. With the new regime I never go off to the same extent..... though I can quite suddenly go off once the two have worn off, especially if I forget to maintain good timing. Glad you are feeling the benefit, and hope that this will give hope to some of those who are struggling.

Happy Christmas to all
Lindy
