Ok I will start with the good points about this pill. It gives you a tone of energy. I am getting so much done at work and around the house because i can keep going and going…Holy toledo. Also it pretty much completely takes away your hunger. To the point where you have to remind yourself to grab something just to put something in your stomach. The bad- One day I took two pills at once and drank a couple cups of coffee and then felt so sick to my stomach and was super jittery and headachy all day. I didn’t want to take any more pills after that, but after a couple days I got over it. The key is don’t take any more than one pill at a time and make sure you keep a little something in your stomach throughout the day. I lost 12 lbs in 2 weeks. Good Luck!
