Yes, it's really hard for people that already regularly drink sugar water to quit the sugar water, but it's not very hard for those that don't drink it regularly to abstain indefinitely. The reason is the gut microbome, which drives your cravings. If you regularly drink it, you have more of the types of gut bacteria that consume it, and they tell your brain to give them more. If you don't regularly drink it, you don't have enough of those types of bacteria to make a dent in your cravings. In other words, you really are what you eat (or more precisely you are what eats what you eat).
