Eat Reissell. I don't know much about this kind. It belongs to the kind that regular pharmacies don't sell, but the effect is very good. It's just that people feel a little uncomfortable, don't have diarrhea, don't want to eat, and get thirsty. Some people will feel flustered and bored, probably because they don't eat. But the effect is very good, they can lose 5 to 10 kg a week. However, they should pay attention to their diet after losing it.
