Musannaf Ibn Abi Shayba 24:27

Zayd ibn al-Hubab narrated to us, from Husayn ibn Waqid, who said: Abdullah ibn Buraydah narrated to us. He said: I and my father entered upon Mu'awiyah. He seated my father upon the couch, and food was brought, so we ate. Then a drink was brought, and he drank. Mu'awiyah said: "There is nothing that I used to find delicious when I was a young man that I take today, except for milk; for I take it just as I used to take it before today."
