Well it seems to work for most people most of the time. We must be careful and try to get more evidence that it is safe with PD meds. It does seem to be fairly mild so far. Several of us have taken grapejuice with our meds for days without any ill effects.
Wendy is right, there are a lot of variables, iit does not work every time. I have had just one failure, when it did not take effect. We need to build up experience to know do we take the juice before or after the meds. does one glass of juice last all day, or must it be taken throughout the day in small doses. What is the optimum dose level. Yesterday, I tried taking a glass of juice in the middle of the regime at 11-00am when I take a 50mg Stavelo, which normally lasts until 2-00pm, This time I switched off at 4-00pm, so an extra 2 hours. I took the juice at 11-30am, ie half an hour after taking the Stavelo.
It works more often than it fails, but it will be very interesting to find out why it fails on some occasions.
