I tried to drink the unsweetened grape fruit juice, it littarly made me throw up. I did it for 8 days. But I pucked every time! I recently heard about a "grapefruit pill" for dieting. Has anyone heard of it or tried it? I know alot of people who really lost weight drinking the grapefruit juice. But I can NOT do it. I would love to know more about the pill, does it work as good as the juice?
