I think the effect of the first generation is better, and the weight loss effect is quite obvious, but the side effects are also great.

My heart will beat faster, I will feel difficult to breathe, and I will return to normal after 8 days of insomnia, but if I don't eat, I will actually bounce back. As long as the appetite is well controlled, it will rebound by about 4 pounds, which is not very powerful, but it will not work if you eat too much. This is my experience, everyone's situation is different.
