All I can really tell you is that there is an interaction with SOMETHING
in grapefruit, especially the juice, that increases the drug level
in your system. Good thing? Bad thing? Xanax has such a short half-life that if you took a dose at night and ate a boatload of grapefruit in the morning, I don't THINK anything really horrible would happen. I personally have just learned to live without grapefruit and done away with one more thing to worry about. I am totally addicted to Kiwi now!
