Amulet of the Drunkard

From Explorer's Guide to Wildemount, page 265.

Description
Wondrous item, uncommon.

This amulet smells of old, ale-stained wood. While wearing it, you can regain 4d4 + 4 hit points when you drink a pint of beer, ale, mead, or wine. Once the amulet has restored hit points, it can't do so again until the next dawn.
