I used it, but it didn't take long, only half a month, but I lost 3 pounds, but it was very uncomfortable. If you have a bad stomach, you don't want to use it. No matter what method you stick to, follow a regular lifestyle, eat well in the morning, eat well in the afternoon, eat less at night and exercise more. I think I will gradually lose weight! Extreme methods are not recommended, which is not good for your health. Even if it is reduced, it is easy to rebound!
