ugh, I went on vacation and my back and knee have been messed up. I've not been to the gym since, and this past weekend I helped a friend move. Now my back is hurting again. With classes starting now, I'm just trying to get on a proper sleep schedule. I literally work an 8 hour shift straight into a 3 hour night class 3-4 days a week. I need to start working out in the mornings, but that may take time until my sleep schedule is adjusted correctly (almost there. I actually went to bed before 1 AM last night!).
