I had better not drink. I bought two packs as soon as I finished the first pack. I felt uncomfortable and tired. At that time, I thought maybe I was tired from work and didn't pay much attention. Thin is not obvious. I may lose four or five pounds after drinking a pack, or five or six pounds! At least it worked. In order to lose weight, I choose to buy a second pack. After drinking the second bag for four or five days, people feel very uncomfortable, with headache, chest tightness, vomiting, no appetite, no desire to eat at all, and no strength. I don't know if it's because of the coffee, but I decided to stop the second bag of coffee and go to the hospital for a check-up. .
