I tried this also, just the way it said to and my sugar was actually higher. In all fairness, I was sick at the time and I know that it may cause your sugar to rise. I called after using it for six days and canceled and yet I got billed $64.98 on my credit card. When I called, they said that a month supply had been sent out back in August, well I didn't get it. So I was told they would give me a 40 dollar credit back to my card for the one I didn't get. It's really sad when you have to pay for something you don't get. It's very poor company policy to me, but a heck of a way for them to make money.
Bottom Line: No, I would not recommend this to a friend
