I have been a McDonalds customer since I was a child- 30+ years. I too had an allergic reaction to the Mocha Frappe iced coffee. I have NO known allergies to nuts, soy, wheat, milk or anything, and have consumed them without a problem ever. But after I drank the mocha my top lip immediately began to swell. I took two benadryl and appliedband a cold compress. My lips were still swollen so I took two more. But thankfully no difficulty breathing.
