Query: Doesn't Work

I tried this in the hope that it would help me cut a few calories, but alas these things don't do much to curb your appetite. I tried it for a full month and drinking one for breakfast and lunch, but was always starving afterwards. I should have known that this probably wouldn't work, there is no magic bullet with this type of thing.The flavor is ok, it definitely tastes better with milk. But if you want to bring it to work its a pain to have to bring a separate container full of milk to mix it, water makes it a lot easier, but the flavor is really lacking.
