Maybe I'm missing something, but I'm not even sure how blister packs help protect against accidental overdose beyond the protection you'd get from just counting the pills in the bottle. In either case, you could accidentally skip a day and double dose later on based on the number of pills remaining, especially if you aren't sure what day you started taking the medication. I can definitely see the benefit of a product that doesn't rely on user reporting to track doses.

The point as I understand/was taught it in school is that the time it would take you to pop out enough* e.g. paracetamol to do really serious lasting harm (vs. 'just' being quite sick or needing stomach pumped) gives a sort of 'cool-down' or re-evaluation period, or requires significant planning, whereas a bottle can be downed impulsively.

(* and that if you're taking them as you go, you'll probably be physically incapable/less inclined to continue far enough after a certain point)

Ah, I hadn't even thought of that, but it makes sense. It certainly can't hurt!
