I can't make myself drink water and coconut water taste like dirt to me. What else is good to keep you hydrated?
Know you probably don't wanna hear this but I can tell you from first hand experience when it comes to really hydrating there simply is nothing better than water, period. Pure, clean water.
A simple water filter is always great to have. Cuts down the cost quite a bit.
Since I was notoriously bad about hydrating myself I also got this HydroCoach app to remind myself. Sounds ridiculous but it helps.
Having a girlfriend to punch you when you're not drinking enough also helps
My main tip is to stop thinking of hydration as something that's supposed to be "enjoyed" and more of something that's a necessity, because it is.
Stuff like ice-tea, fruit juice etc etc tends to be laden with sugar. If you keep using that stuff to really hydrate i.e. drink a minimum of 2.3 liters a day, you're gonna blow up and go diabetic from all the sugar.
