Works for Appetite!
I honestly expected this to be like any other product that works for everyone else, except me. Well, it actually curbs my appetite. I don't notice a flavor. I do take Raspberry Keytones on lunch as well. The problem is, I actually need to remind myself to eat. I haven't lost any weight from it, but I've only been on it a week. I'm dealing with a back injury and the meds they put me on made me gain so much weight, especially since i can't go to the gym currently. Since I started taking this, I stopped gaining weight , so that's huge for me. It's definitely worth the money, if you're having issues like me!
