Query: does not work

The first hoodia product I used was Mega-T with hoodia, which worked really well so I decided to try this product. I figured it would work just as well, if not better, since it contains more hoodia than the previous product. However, with this product my appetite did not decrease at all. I was still hungry all the time and I started to gain back the weight I lost while I was on Mega-T.
