I do pack in a small med kit. Typically 3-4 Advil, a couple aspirin, tylenol, a tums, one anti-diarrhea, and one sudafed (meth grade). I also bring in a couple waterproof bandaids, a single serving antiseptic, and a small square of leukotape. Most of that never gets used, and is packed over and over. You can spot the med kit in this picture in a small pill pouch.
I'll pack in a second mini-bic. One that stays in my pocket, one for our group to constantly loose throughout the trip. Same for that extra TP packet. I'd rather have it with, then find myself in the woods running short. Got a whistle in there too that I don't think I've ever used on the trail.
Most of my hikes, I'll plan to be at the site before dark. I'll still bring a reasonable headlamp.
