Ah, the life of a teacher.
It took me a few years to retrain my body not to want lunch at 11:08. The thing is, I still get up at 4:30- 5-ish a couple of days a week, and really, not later than 6 other days. However, I don't get to work until 9 or 10 and 2/3 days I work until 6 or 7. It's hard to go to bed at 9, when you get home at 7:30. And, it's wreaked havoc on my work out schedule. This is why I changed gyms, so I wasn't getting up for boot camp on the days I don't work. And no more after work rides. However, I do ride at 5 AM, which some think is crazy.
