1. Lack of sleep! It doesn't feel normal to go to bed at 7pm when it's still bright outside, so I'm always tired.
2. Lack of an evening social life. It's a challenge to go out in the evenings, so I miss a lot of dinners & such.
3. Weird meal hours. I can always eat, but it feels normal to have a meal at 3pm, but nobody seems to want to go to dinner at that time! lol!
