    My first question about this study would be: Did they analyze a sub-group who are NOT regular coffee drinkers?
    If not, it could be that MOST of the participants are already addicted to caffeine and therefore need the coffee.
    From personal experience, I can say that back when I drank no coffee, I had no problem getting up at 5 am to start my day at the gym and then move on to my studies.
    For the past few years, I’ve been an avid coffee drinker and I definitely can’t say that I have more energy overall; what I do find is that without the coffee, I can’t function as well as I did when I didn’t drink it at all.
    There’s nothing scientific in my anecdote. I just wonder sometimes if we coffee drinkers need coffee to just get back to “normal” and not really to a superior state of functioning.

    BEST coffee? Death Wish coffee. Can’t live without it. You can only buy it on the web. Look it up, buy a pound and I promise, you’ll fall in love with coffee again.

    This is one study and I haven’t had time to read through it all yet, but I do know that one thing that studies have *consistently* proved to improve memory is getting enough sleep after learning, and getting enough sleep in general. Two of the most important things in life according to research: sleep and exercise. You get enough of both and you’re 90% on your way to being all set up.
