Since I've started weighing myself daily, my day often starts off on a sour note.
I sometimes want to just whine and cry (and sometimes I actually do) but then it's off to the gym! 99% of the time I feel better once I'm done working out; my mood is much improved, my body is awake, and I feel like I've accomplished something.
If I don't workout not only am I lethargic, but I'm cranky! It also makes me feel like "well, since I didn't workout and I feel like crap I'm going to eat like crap!"... Yes, totally logical right?
I think that at this point I am one of those people that is both mentally and physically addicted to exercise.
