Who else feels nauseous AFTER eating?

When I'm not pregnant, I can literally snack and eat all day. I can't now that I'm pregnant, (12w+1d) and wait until I'm actually hungry to eat. By then, I'm usually starving, but then after I eat, I feel nauseous, and make enough saliva to fill up a gallon bucket. (Exaggeration, but sure feels like it!) Does anyone else feel this way?
