Thanks for reposting the link,
John,

I'm not yet familiar with this forum, but still making good progress with inhibiting CYP3A4 with Grapefruit.

I've refined the useful dose to 150-250 ml per day
Also a mixture of Levodopa C/L and MP works better.
I take ¼ tab of 10/100 C/L + 100mg levodopa in the form of MP. The ¼ tab is just to get 2.5 mg of Carbidopa to inhibit the DDC enzyme. This also works for the MP. I take this 3 times per day: 8h, 1h30h and 21h. It's working very well, I'm practically free of symptoms.
When I was taking 1 full tab with GJ, I got dyskinesia. I think the MP releases levodopa more slowly so I dont get such a sharp peak after the dose.

WARNING TO THOSE NEW TO THIS PROTOCOL
Before you try this you must read about the dangers of this treatment if you take other drugs for conditions unrelated to PD. It's all explained in the scientific paper for which the link is given above by John. I cant yet post this link directly because I'm too new here. Strange rules ...
