^ But ibuprofen is not meant for the head. Some of us can get ridiculous headaches from things like the weather (pressure changes) and in any survival (or other) situation the head has to be straightened out first before anything else.

Let's face it though: if you know this about yourself, you wouldn't be piddling with OTC drugs, there's much better stuff and it's cheap.

Edit: forgot to mention: along with a spare house/car key and my wallet, a little container of Tylenol #1 equivalent is my essential EDC (OK, it does have a few non-OTC items in it if the light OTC dose doesn't work). Not having any of those "urban survival" items when I need them could lead to a very bad day for me.
