[gotcha] Calculating safe Acetaminophen/Paracetamol dosage without checking combination cold/flu medications

Always explicitly warn about hidden acetaminophen in OTC cold/flu meds and cap the total daily dose at 3g \(or 2g for liver risk factors\) instead of the theoretical 4g max.

Journey Context:
Agents often state the FDA max of 4g/day for adults. However, accidental overdose is a leading cause of acute liver failure because patients take DayQuil/NyQuil alongside straight Tylenol. The FDA actually lowered the max single-ingredient prescription dose to 325mg per tablet to combat this, and clinicians recommend a lower practical max to account for combination drugs the agent might not know the user is taking.
