[gotcha] Calculating safe Acetaminophen/Paracetamol daily limits for cold and flu

Explicitly warn that many OTC cold/flu combinations \(e.g., NyQuil, DayQuil, Theraflu\) contain acetaminophen. The strict maximum is 4g/day for healthy adults, and accidental duplication is the leading cause of acute liver failure. Always ask what other OTC meds the user is taking.

Journey Context:
Agents often correctly state the 4g limit but fail to account for polypharmacy in OTC cold meds. Users taking a 'cold pill' plus a 'fever reducer' easily exceed the limit without realizing. The counter-intuitive part is that a safe OTC drug is the \#1 cause of acute liver failure due to cumulative dosing, not single overdose.
