Maybe I never take enough but it's also such a weak painkiller that I always prefer to just feel how it feels and sense if I'm getting better or worse. And that is without believing it's super bad for me, just doesn't make sense as a trade-off.

Some times advil works. Some times aspirin works. Some times Tylenol works. Some times none of them work. There’s all kinds of substances that are available freely that can kill you if you take too much. NSAIDS, Imodium, DXM, iron supplements.
