I'm wondering if there is a problem with the Wii being on the carpet? I do have risers on it, but I just do not see how there can be that big of a disparity. Either reported result is possible. From past experience, the 2.5 is more typical after the slow days and then the big gain. Which, I do believe I've decided, was a mid-cycle bout of water retention.
I've added digestive enzymes and being more diligent about the probiotics. I've also ordered some supplements from Mercola's website that might help.
