drink tap water.
whats that? you dont like the taste? i have a solution. make tea.
I like Bigelow mint medley, and raspberry zinger from Celestial seasonings.
These teas are not caffinated, tasty as fuck and make just about any tap water drinkable. i recommend buying a large 2.5 gallon water pitcher with spigot for all you tea storage needs. keep that shit chilled and in the fridge.
easiest way to drink 8-12 glasses of water a day. Oh yeah, DONT sweeten it. use your other sense, your sense of smell. smell as you drink, inhale that heavenly aroma deep into your nostrils, now as you inhale, drink. I promise that you will taste between 25-50% more mint/raspberry lemons.
