Gwern, I apologize for the sarcasm; it wasn't called for. As I said, I'm new here, and I guess I'm not clicking "show more above" as much as I should.

However, a link still would have been helpful. As someone who had never read your article, I had no way of knowing that a link to "Melatonin" contained an extensive discussion about willpower and procrastination. It looked to me like a biological solution, i.e., a solution that was ignoring my real concerns, so I ignored it.

Having now read your article, I agree that taking a drug that predictably made you very tired in about half an hour could be one good option for fighting the urge to stay up for no reason, and I also think that the health risks of taking melatonin long-term -- especially at times when I'm already tired -- could be significant. I may give it a try if other strategies fail.
