For the last four to six weeks, I've been avoiding caffeine. Not for any particular reason... just avoiding caffeine. I wanted to see what it would be like, if I'd be tired all the time, or if it would improve my ability to sleep. I wanted to see if I'd be able to do it—if I was really addicted or just felt that way.
But it was easy. I don't have any kind of dependence on caffiene, it seems. I didn't quite stop "cold turkey"; maybe I should have. I mixed it half and half for a few days. But I've gone days without any caffeinated beverages at all now, down from at least six to as many as ten a day. I don't feel any effects, positive or negative. I'm not any more tired, and it isn't any easier to get to bed. I didn't miss it at all.
Oh well. I've gotten used to the taste of caffeine free Diet Coke and Diet Pepsi now; it's not really any worse than the regular kinds, just different. All in all, a pretty pointless little experiment. About all that I can anecdotally say now is that caffeine doesn't help me wake up in the morning after all. Any couple cans of something cold is fine enough.
