I had mine on May 6. Down 28 pounds so far (345-317). Only 2 lbs. lost in the past week, though. I was discouraged, but in reading posts here I understand this may be just a stall or a plateau. I'm doing what they tell me to do, and I'm walking 5-6 times a week. I have more energy and though I still use a CPAP, I noticed I've been sleeping much better the last few nights. For the first time since my marriage last October, my wife was able to put her arms completely around me.
