sated--or satiated comes to mind
but in the venacular, "I'm stuffed!" --but it tend to apply to any over eating (like after thanksgiving dinner)

the sick feeling-- might well be 'upset stomach'-- does any one remember "That's one greasy meatball!" commercail? what words were used to describe what the actor was feeling and how to make him feel better..

--bloatted--is currently being use in one commercial.. the feeling ones body is distended and blown up with food and gas..
