I don't know the answer to your question but clearly your neuro doesn't either. It "CAN'T work that fast?" How does he know? I bet if you asked him to explain the specific mechanisms by which Stalevo works and the particular receptors it targets, he would not be able to do it.

Sorry, but his/her comment ticks me off. If YOU notice a difference, that's all that matters in my book. Everyone is different. If you are lucky enough to find something that helps, hallelujah! I hope it continues to work like this for you.
