[gotcha] Calculating safe Acetaminophen/Paracetamol dosage without checking for multi-drug combinations

Always warn that maximum daily limits \(4g/day for adults\) apply to \*all\* sources of acetaminophen combined, including OTC cold/flu remedies, before calculating or confirming any dose.

Journey Context:
Agents often correctly calculate dose by weight or standard adult limits, but fail to account for OTC combination drugs. Users silently stack NyQuil/DayQuil with straight Tylenol, leading to acute liver failure. The counter-intuitive trap is that a 'safe' dose of Drug A \+ a 'safe' dose of Drug B \(which contains A\) equals a lethal dose of A.
