How can you reach adulthood and think it's ok to take 3 or 4x the specific dose of any medication? If you're in that much pain you go to a doctor. Which makes me think maybe the issue is the private health system and not the drug.

Conversely, my grandmother's Alzheimer's became apparent when she was overdosing on either ibuprofen or aspirin, I forget which.

She would take a dose for a headache, ten minutes later she'd forgotten so she'd take another dose, ten minutes later, she had forgotten, take another dose, rinse and repeat until it's time for a trip to the hospital.

Maybe it wasn't ten minutes between, probably fewer given how much she'd ended up taking. This happened thirty or so years ago.
