You can drink two bags a day, but only in the morning, because you don't know if you want to eat midnight snack at night and you can't eat on an empty stomach, so drinking solid drinks alone will not be fully absorbed, which will destroy the nutrients. You can also divide it into morning and evening, drink it on an empty stomach after washing in the morning and have breakfast after 20 minutes. And drink it before going to bed at night, preferably on an empty stomach. Let the stomach fully digest and absorb solid drinks. As for the remarkable effect, if there is any remarkable effect, you will revert to the original state if you don't persist. Also, it can be used as a drink after the effect comes out, which is basically harmless.
