Hi Rick,
If that is a short literature search, gosh!!
I would love to know if anyone else experiences the boost in on time. However, take it carefully, interactions with certain drugs are very bad. Certainly I tried it for 2 days and had no bad symptoms or side effects. I don't think big pharma will be too pleased, probably why it is not widely known.
There is a list of 50 drugs where grapefruit juice intereacts with them, but I have not managed to find it yet.
Thanks again for your mamouth list of refs.
Ron
