According to this article in Science Translational Medicine (bit.ly/CoffeeZzz), late night coffee can really throw off your sleep patterns. I understand, sometime you have to stay awake, and coffee is very effective for that, but I wouldn’t do it on a regular basis.
The roasting process of coffee beans occurs at a high enough temp to destroy some of the caffeine molecules contained within coffee. So, contrary to expectation, light roast coffees have more caffeine than dark roast. Espresso has a high caffeine content (~150 mg) for its volume of liquid (~2 oz.), but less than a normal cup of coffee (~235mg in 12 oz.). Here’s a great list of common coffee drinks and their caffeine content: bit.ly/CaffeineList.
