I bought two boxes, one for eating before dinner every day at home, and the other for eating before meals when I go to work. I bought it with the mentality of giving it a try in order to absorb less sugar and carbon water. At present, it works very well when taken with black ginger. The fat around my abdomen that I couldn't lose at ordinary times is slowly decreasing. This will not make you very thin all of a sudden. It should be combined with exercise and a reasonable diet to lose stubborn fat. After pregnancy, especially the abdomen, no matter how much exercise it takes, it doesn't get smaller. After taking this, it is obvious that the fat on my abdomen and thighs has gradually disappeared. I didn't feel any side effects. I felt sleepy at the beginning of taking it, but I didn't feel sleepy anymore later.
