I used this a few months back to lose a few pounds. I lost 12 in with 21 day fix program! It wasn't very easy, but if something is difficult you just do a varied position. I love it, and I plan on using again. It also works well with the portion cups.
Another pick me up when I desperately need caffeine. It doesn't taste like the typical Mountain Dew, and has a variety of flavors. The sugar content of higher than I like, but it's not out of control where you'd skip it. It's one of my favorite drinks.
