Input: I have used this product for a month now with no changes noted. It has however improved my appetite while it lasted. My stomach still rumbles when I'm taking them and the fiber is so fine you really seem to be swallowing pieces of your food. If they would come up with some new packaging that didn't make me gag, I'd buy them. However, they are not cheap but then again all sugar supplements are. And I don't eat a lot anyway. Just add water as needed and you're good.
Output:
Bad review
