A most intriguing comment on Tim Ferriss’s excellent post about how to sleep better:

The single biggest factor for me has been the elimination of all dairy products from my diet. I have experimented with this over 4 years now and it is clear the most benefit is achieved with the most radical approach to this. In other words, removing dairy products completely from my diet has the biggest benefit. Yes this means no chocolate, no products with whey in them, no milk, yoghurt etc etc. it’s also interesting to see how difficult this is to do, but the benefits are so astounding from an energetic lifestyle point of view that I do it for long periods of time at a stretch.
