Word for "A feeling of lethargy experienced after eating a meal"

From this link, I found the word to be "the Itis".

Is there a synonym for this word?

"I got the worst case of ______ after that cheese steak with fries".


Solution 1:

Post-prandial somnolence, post-prandial sleepiness, or post-prandial fatigue. (The hyphen is optional.)

Food coma

See Wikipedia:

Postprandial somnolence (colloquially known as the itis, food coma, after dinner dip, or postprandial sleep) is a normal state of drowsiness or lassitude following a meal.
