Trouble Drinking Water

It is probably to do with viscosity and surface adhesion properties of liquids. Adding other things to water, such as milk, oat milk, sugar etc. will change these properties and change the 'mouth feel'.  It doesn't matter that you do not like drinking water as anything with a high water content will work to hydrate you. Even low alcohol drinks will do the same. Back in the day, when water was not safe to drink, due to disease organisms and chemical contamination, people drank beer - even at breakfast ('small beer' very low in alcohol).

If you were to add milk to water you'd have to have coffee in it at least otherwise it tastes awful.

But it's not really about not liking to drink water, i actually wish i could drink more of it without all the extras like coffee/oat milk. It's a feeling problem like sickness.
