To be honest, when I got the injection, I noticed the effect after the 3rd time, but as soon as I let go of the diet, it started to go away and I felt even more hungry than before the injection . Even after getting the injection, I think I still have to control my diet well . Oh, and the injection was really painful. I got hit 5 times, and every time I got hit, I was shocked and wondered why I had gained weight. Sigh... Now I just have to exercise and eat less...
