You're not drinking coffee though, you're, I'm laughing here because I keep having to reiterate this...
You're not consuming coffee because you like coffee. That's obvious. You like the buzz. You like the stimulant effect of the drug caffeine. I am comparing in the motions of a junkie... I know caffeine addicts that are bigger caffeine junkies than some hard drug users I know. It's neither here nor there, but I could care less if you shoot heroin, let alone drink coffee or take caffeine pills. If it helps you do your job and it doesn't ruin your life, fine. Lord knows I'm sick this week during a week that I simply can not be sick, I'm using Aleve and Mountain Dew like they're going out of style.
I just wanted to point out that plenty of people are very productive without caffeine. Seeing as caffeine doesn't give you abnormal abilities... it seems to be that it would be better to not be dependent on it, or not use it as a crutch, or whatever it is that you're using it for.
