The body takes 2 to 3 days to digest food. A large amount of food cannot be properly digested and will take longer and all the digestive bacteria must help to digest that amount of food making it difficult to digest all the food in time. Food floods your stomach and causes a reaction. Especially when you drink milk. Milk is an alkali and we need acid in our stomach to survive. Milk neutralizes the acid making it defective. Meaning teh digestive bacteria can’t work properly. So with all this going on the stomach won’t be able ti contain everything and will pop it back up the mouth hole until it’s enough to manage. So in conclusion I couldn’t take a shit until I barfed.
