Hello friend, according to your description, after taking diet pills for three days, my heart beat faster, my body was weak, I lost my appetite and felt dizzy. I think these are the side effects caused by diet pills, so I suggest you try not to take diet pills again in the future, because this will not only help you lose weight, but even affect your health.

So I suggest that you lose weight naturally in the future, and it is best to achieve the effect of losing weight through exercise and diet control. First of all, don't eat too greasy food, eat more fruits and vegetables and reduce calorie intake. Slim down slowly, and then keep exercising every day, by jogging. Playing basketball and other sports consumes more calories and helps to lose weight. I hope my answer can help you.
