Ól cen íttu cen mescai.
Proind shéim cen sáith cen gortai.
(Drinking * without * thirst * without * drunkenness
Meal * light * without * fullness * without * hunger)
In drinking, neither thirsty nor drunk.
In eating, neither sated nor hungry.
This dietary advice comes to us in the form of a marginal note on page 100 of the Leabhar Breac, which is quoted s.v. "séim" in DIL.
