One thing to consider is that your relationship with taste might need to be re-examined.

Human beings can go most places in the world and find food. Taste is a big part of our ability to do so as a species, sure, but the fact remains that being able to eat/drink solely to satiate your desires (rather than survival) is actually an abnormality if we compare it to the rest of human history. In a sense, it is a privilege to simply be able to say ‘no’ to something strictly based on the flavor.

Try to guage it based on how you feel rather than how it tastes. You should be able to feel the difference between how a day with only water feels vs a day without water (I’m not including beer or soda here, yes it can keep you hydrated no it is not a solution to hydration unless you’re trapped in a desert). If it’s hard for you to notice a difference, give it a week. Being regularly hydrated should effect how you feel at every part of the day, especially in the mornings.
