Monks' Rules (Author: Columbanus Hibernus)

Rule 6

6

But if any has made himself drunk and vomited, or being overfed, for this reason has vomited the sacrifice, let him do penance forty days.

However, if he is forced by ill health to vomit the sacrifice, let him do penance seven days. If any has lost the sacrifice itself, let him do penance for a year.
