[gotcha] Recommending max daily dose of acetaminophen without checking combination medications

Always explicitly warn about hidden acetaminophen in cold/flu/sleep OTC medications before stating the 4000mg/day limit; advise calculating the total from all sources.

Journey Context:
Agents often just parrot the FDA maximum daily dose. Users routinely mix drugs like NyQuil and Tylenol for concurrent symptoms, leading to accidental acute liver failure. The trap is treating the drug in isolation rather than evaluating the user's total polypharmacy load, which is the leading cause of acute liver failure in the US.
