Your body’s signal for releasing stool at the end of the intestine is when more food comes up at the beginning. However, as you are not consuming food the last bit of stool is kept in your intestines by your body, however that stool eventually starts becoming toxic to the body over time. So the body expels that too. Hope that made sense
If you chug a bunch of snake juice you’ll pass real quick as your body shoves water into your intestines. Like a bucket running over. Not a remedy but doesn’t really hurt if your snake juice is nice and diluted.
