I came across this idea from a friend parky.My jerking always seamed worse if I didn't get good sleep and also when I did sleep well I could delay my morning dose til afternoon.Her doctor said early in our disease we replenish our dopimine.In late stage we dont get the sleep renewel.Its a good way to measure our progression.
This applies to me too: I get up feeling good, and I can go hours without my morning dose. When I do take my dose, until it kicks in I feel worse. I think this shows that even 12 years after diagnosis I am still producing dopamine and storing it.
