It's fine that you don't think so, but that's how it was worded.

"Casual" painkiller users tend to take what's on hand and aren't trying to build three medication stacks with caffeine.

You're being very defensive as if the person who started their comment with "fun fact" had instead started it with "you're an idiot doing wrong things" - nobody was criticising you, nor claiming they knew your frequency of use. They were sharing useful information on a public forum that, if not useful to you, would still be useful to other people who read your first comment.

Then the comment is for others, not you.

Just because you yourself might be physically fit, that doesn't mean we don't have an obesity epidemic in NA. Apply this same principle to my earlier statement about ibuprofen.
