Dear Upward, My days are crammed with work, kids, and responsibilities. By the time I fall into bed it's late, and I'm up again before sunrise. On rare weekends when I could sleep in, my body refuses. I see two options: (1) wake up naturally and hope to drift back to sleep a few times, or (2) knock myself out with sleep meds or herbal remedies. Which path actually helps my body recover? What's worse for my health: too little sleep or too much medication? —Running on Empty
