Most people do get enough water, tea, diet sodas or energy drinks, Gatorade, etc. most drinks are 95-99% water and have the same hydration effect as a glass of water. Caffeine isn’t a strong enough diuretic to actually have any impact in 99.99% of cases. You would basically have to over dose on it and kill yourself before it became a real problem for water intake.

The problem almost always is lack of veggies, exercise, fruits, and lack of sleep.

Hydrohomies have caused a huge amount of problems with the whole drink more water thing. Over focus on a problem that doesn’t actually exist while being toxic and aggressive at anyone who tries to correct them.

Calorie intake from drinks is a larger issue then lack of water. Which is solved via artifical sweetener or drinks that don’t normally contain large amounts of calories. Assuming of course your trying to lose weight or it’s hampering your ability to eat other food stuffs such as veggies.

Seriously people just eat some more veggies, walk a bit more and go to bed an hour earlier. It will do infinity more for you then drink more water.
