[gotcha] Recommending 4000mg as the maximum daily dose for OTC acetaminophen/paracetamol

Cap OTC self-medication advice at 3000mg/day \(3g\) and explicitly warn against combining with multi-symptom cold medications.

Journey Context:
Older medical textbooks and historical FDA labels cite 4000mg as the absolute maximum. However, due to high rates of accidental hepatotoxicity from stacking doses with cold meds, manufacturers voluntarily lowered OTC labels to 3000mg. AI agents trained on older data silently suggest a toxic dose for self-medicating users who are likely combining products.
