It's not getting much better. The physical symptoms have disappeared, but my attention span is still down. Sleep cycle seems to be less disrupted, but that's probably just because the wife and children are out of town. Still suffering from mild aphasia, forgetfulness, and slight but noticeable sluggishness. This is a bit worrying. We're talking coffee here, not heroin or methamphetamine. Surely I should be feeling more normal by now. A possible clue: drinking herb tea seems to help a little. But only a little; and I dislike pretty much all of the sorts of herb tea that are available around here. At this point I'm going for a month. One more week. After that... I don't know.
