I haven't gotten bored with water yet, but it might be the youngster in me kicking back in, since I drank A LOT of water when I was a kid. Granted, I've also been feeling random cramping and pains and have found water to alleviate those a little, so that's been motivation for me to stick with the water. Sometimes, I'll mix Gatorade in with the water to add flavor and make sure I'm keeping up on my electrolytes.
