I'm amazed that yet another debate has occurred on the support forums.
The grapefruit effect was accidently discovered about ten years ago... and while there are pharmacists that caution against drinking or eating it while on various medications, I am led to believe it's because of the haphazardness of the patient himself and not the real worry over the interactions. By this I mean that since everyone is different, and some might have some affect, it's because they can't remember what they ate or drank when in determining when they take their meds.imo
I do think I read that Dr Wylie was discussing PSYCH meds, and I'll go with him on this.
