Gerry,

You write:

"I currently take 34.5 g of Mucuna (40% levodopa) daily plus 45 g of tyrosine."

That's approximately 14g of levodopa per day, plus whatever may come from the tyrosine. This compares with for most people on C/L of under 1g (= 1000mg) per day.

I think it would be really useful to everyone if we understood why these numbers are so different.

For a start, you don't take carbidopa. Wikipedia states that [1]:

"Carbidopa reduces the amount of levodopa required to produce a given response by about 75% ..."

That reduces the comparable level from 14g to approximately 3g.

Are there any other corrections to make?

How do you avoid nausea with these amounts of levodopa?
