I actually beefed mine up in some ways (and pared it down in others)

That sounds right, adapating it to your actual needs! 😀

About 5 years ago my first aid kit was a gallon ziploc my partner prepared. It had boxes of band-aids, bottles of pills, bags of lozenges, multiple packs of moleskin, a fabric bandage, rolls of tape, a roll of antacid, etc. Whenever we would go on a hike, short or long, we’d pack it automatically. It weighed well over a lb and after reviewing it critically I realized there was lots of duplication and that I didn’t know what some of it was even for. I’ve managed to downsize that thing to a quart-size ziploc for use as a couple, but when I go solo I carry 20 ibuprofen, 3 Sudafed, 2 Loperamide and tweezers in a tiny baggie. I also carry a patch or 2 of leukotape, a needle, floss and mini scissors and one Ibuprofen PM per night. In the last 3 years I’ve used all of it at least once except the Sudafed and Loperamide (🤞). Additional risk mitigation is choosing the right trips at the right time of year and appropriate preparation.
