💡 PRN medications still count. OTCs still count.

A PRN benzo taken at 2 AM still affects morning ambulation.
Diphenhydramine taken "for sleep" 2-3 nights/week = regular anticholinergic exposure.

Hidden OTC FRIDs:
• Tylenol PM, Advil PM → diphenhydramine
• ZzzQuil → diphenhydramine
• Unisom → doxylamine

Ask: "Are you taking anything for sleep, allergies, or pain that you buy without a prescription?"
