Just lately, my sensitivity has been less pronounced, I'm happy to report. Or, rather, my level of exhaustion is such that I fall asleep regularly throughout the day and sleep more or less normally (for me) at night even with extra caffeine. And boy am I ever craving it. For the first time, I'm appreciating the high, not just taking advantage of the illusion of energy. Why, I had an extra eight ounces this morning and just made another pot (another sixteen ounces, made with an extra scoop of coffee, so it's almost exactly the way I like it). It's all very exciting--not least because I broke my coffee grinder in the process (it was a genuine accident, I promise: the top got caught in my sleeve and flew off the counter, and the switch portion shattered on impact with the floor), so now I can justify purchasing a burr grinder.
Like I said--exciting.
