Do you feel/look fat after a large meal?

Anyone else eat a lot of food and feel cruddy afterwards. Then you happen to look in the mirror and you say to yourself "OMG, I look huge!" Sometimes I feel like that after eating and the day following and It sucks. I was just wondering if anyone else gets that way and if you physically do look bigger or if it is just your mind playing a game from all the sugar/carbs that you ingest or if maybe it is a combination of each.
