The good news is that I'm no longer addicted to caffeine. I discovered in grad school that I was wildly addicted to caffeine, such that if I got as far as about 2pm without having had some coffee, I'd end up with a mind-blowing headache. Often earlier, since I was also working part time at IBM and if I wasn't at school by 9am, I was at work, and probably working on my third mocha by 10am. It wasn't unusual for me to sleep in on Saturdays, only to wake up about 11 with a pounding in my head that would kill an elk. Which would go away within about 10 minutes of my first cup of coffee, or an aspirin laced with caffeine. So I was pretty addicted.
Since then I've been weaning myself off of "massive" doses of caffeine, but always careful to have my 2 cups of coffee in the morning, or equivalent. And lately I've been able to go a day without coffee, but (never let it be said that aversion therapy doesn't work) I always had some coffee sometime, just to avoid the headache.
But this weekend, I went the whole weekend, that is, from about 3pm Friday (when I had some diet Dr Pepper) to about 9am Monday morning (when I had some coffee with breakfast), without a drop. Okay, it helps that I slept most of the weekend, so there were only so many hours a day to imbibe anyway. But no cravings, no headache, no problem. Not much in the way of useful consciousness, but that's not the point, since caffeine-induced consciousness isn't remarkably useful in the long run anyway.
So progress, of a sort, is slowly being made. Yay me.
