I appreciate his research but have a problem or two with some of the conclusions.
First, although my data was lost when the old forum tanked, I do remember being perplexed by the fact that I did quite well with mucuna sans carbidopa. As I recall, I began my trial figuring a rough increase to compensate for the enzyme action and ended up very much over medicated.
Second, our bodies put a lot of resources into eliminating ldopa in the periphery and there is probably a reason. It might be better if the system was allowed to retain a regulatory power over it.
I do remember that it was a "smoother" drug with less motor problems. And it is a heck of a lot cheaper. A poor man could do a lot with mucuna and dextromethorphan and a bit of ginseng. I can see the state policeman now, "Now, boy, stop your twitching and explain to me why you've got a trunk full of cough syrup, dried roots, and funny beans!"
