good day gone bad...gone good?

So I just realized that I made the goal I set this morning! I drank 9 glasses of water today (that's 72 oz people!) WAAAAAY better than the 2-3 glasses I usually drink. I know it doesn't seem like much, but it was enough to turn my frown upside down! Does anyone else get this crazy emotional (as in worse than PMS) when they start a new eating plan (good or bad)? I think it may be part of the reason that I fall off the band wagon all the time. Not this time though. I refuse.
