I've used it. I don't recommend trying Besunyen. The advertisement is very good, but after drinking for three hours, my stomach will feel uncomfortable, but I don't want to have diarrhea. It's killing me. I called them for advice, and my attitude was not good, so I said, "Drinking to lose weight is not good, and my stomachache is normal, so I can get used to it." What do you mean "habit" ~ ~ It's so irritating.
