I never thought I would love and crave water so much as I did prepping for my first bb contest -- now I kill about about 2 gallons / day. The other thing about getting serious about bb is that I pretty much stopped eating because I enjoyed certain foods. Now I eat because I need the fuel, what I eat will give me the optimal stuff to achieve my bb goals -- after a while it just becomes a way of life. Trust me, if I had a choice between a can of albacore & a big fat burger, you KNOW which one I would take, but I also know which one I would kick myself for eating once it was over.
Now its pretty much a lifestyle. I like the way I feel when I drink lots of water - I'm keeping my system flushed and I can pound out some pretty fantastic workouts! I get really pissed when I dont' have the trusty water bottle w/ me actually....
