You'd think I'd learn what I can get away with. I ignored my caffeine intolerance all during our trip. Once I realized I had accidentally gotten real coffee, I knew I had to either keep up the intake or put up with a headache during my vacation. I decided to postpone the headache and drank caffeine every day to hold off the pain. But today, almost exactly 48 hours after my last dose, I can feel at the back of my head an approaching migraine.
It starts like a dull ache that makes it hard to think and grows till it is a throbbing ache that makes thinking impossible. Sometimes I feel like I'm a little kid, doing something that has inevitable consequences, yet still hopes that THIS TIME it won't work out that way. I can appreciate that worn out saying, "Insanity is doing the same thing over and over again and expecting a different result." So I made an insane choice, hoping that THIS TIME I could get away without a headache. And yet here it comes.
