Your sleep is very important VeganChick. So do catch up on sleep as a priority. Give yourself time. Just stick to healthy meals. Any chance to exercise (even yoga?) during lunch for a short time? As for not biking, don't beat yourself up right now. It'll come back when you're ready.

One of my sisters has this perpetual problem --she is an ER doctor at a hospital and works 2 12 hr. shifts back to back every weekend. She drives 80 km. to work one way and then back. Then she comes home....to her 2 young children and hubby. She jokes: I'm shortening my lifespan by working these night shifts.. I think what she is saying is based on medical studies.. What one do? She is making this choice and wishes to by working part-time only.
