So let's get to the crux of this post. I get tired of eating and drinking in order to sustain the mileage and workouts I'm doing. Sounds weird, I know, but I truly get tired of it. Drinking more means more trips to the bathroom, including getting up in the middle of the night to pee. And since I already don't sleep very well, getting up to pee is a problem.
Eating - It's not that I don't get hungry; I just get tired of trying to figure out what to eat, when to eat, what kind of stash I should keep at work so I can eat little bits throughout the day, etc. I'm also one of those people who has a wholly unrealistic (translates to "I'm an idiot") idea of what her body looks like, so I'm always "afraid" of gaining weight. Besides, extra pounds means more to lug around on the trails.
