My main souce of liquids are juices like apple juice, grape juice, cranberry juice, orange juice.
I seldomly drink pop, but, plain generic cola is fine with me from time to time.
Water when possible (i live in a basement with no tap, just a fridge, my theater, and my computer), on good days when I have time, I'll fill up a pitcher of filtered water to take downstairs and stuff in the fridge.
Alcaholic beverages like low alcohol content drinks, malt liquors like mike's hard lemonade, and my new favorite and I don't know what it's called because i just though it up one day is Vodka, Grenadine and Cherry 7-up mixed preferably with a marchino cherry on top.
