Most people are discussing coffee, but green tea isn't really mentioned. I started limiting my coffee intake maybe 7 years ago and switched to mostly green tea, except for certain occasions.
Green tea doesn't nearly impact my sleep as much, I find it easier to stay hydrated, it doesn't give me jitters but a more calming focus, and it's a lot easier to take the caffeine in slowly, because each cup of genmaicha is maybe 20-30mg of caffeine. A pot is maybe equal to one or two cups of coffee, but with a lot more water, and a steadier slower onset.
