I tried both the Ruby Red grapefruit juice and drinking the juice from fresh grapefruit. In both cases, there was no relief for me and I tried it 2 days in a row. I'm happy for all those folks who've had success but sad to say, the grapefruit juice "cure" did not work for me at all.

Tried several days in a row, no effect whatsoever. Are grapefruits in the US from a different planet?
