I picked mine up on Saturday, but haven't used or taken yet. I am doing takeoff today and tomorrow, and just don't think it necessary while on it. And I forgot it yesterday. I will post after taking. I think it looks interesting, esp. the powder. It was explained to me this way: you can increase the volume of some of your favorite things, but not how it is counted in servings. For example, if you like sour cream, you can mix it with it(can't remember the measurements, sorry) and it increases the volume of it, so it seems you are getting more than you are. I am hoping it is as good as it looks. They are really, really pushing it at my center. Lots of commercials about it. And they anticipated they would run out of the powder by middle of this week, and would possibly be a couple of weeks before they get more. I pre-bought 4 each of the tablets and powder, and the manager sent 1 tablet and 2 powders home with me, saying she did not want them to run out and me want more. She talked like eventually it would be in stock with no worries of running out.
