I definitely remember receiving blister packs, decorated with directions and pill groupings that started with 2 pills, at high intervals like every 6 hours, then tapered to 2 pills every 12 hours toward the end of the first week, then 1 pill every 12 hours for the remainder of the pack, and included strict instructions to use the whole thing.

I got strep throat a few times as a kid. I don't have perfect recall about the details of what I had to take and when or why, though. But I do remember having to vary dosage.

Yes, exactly. And a smart kid might notice that. :)
