[gotcha] Calculating Acetaminophen/Paracetamol max daily dose based only on standalone pills

Always explicitly warn about hidden acetaminophen in combination OTC cold/flu medications \(e.g., NyQuil, DayQuil\) and prescription opioids \(e.g., Percocet, Vicodin\) before calculating or validating safe dosing limits.

Journey Context:
Agents naturally calculate the 4000mg/day adult limit based on the specific pill the user asks about. However, users frequently take multiple overlapping cold medications simultaneously. Acetaminophen overdose is the leading cause of acute liver failure in the US, and the trap is assuming the user only takes the single drug explicitly asked about, missing the polypharmacy context.
