Definitely measure in the beginning or atleast use smaller dishes and be very aware of how much you're eating while you're eating. Remember to take small bites, eat slow, and like others have said wait a few minutes in between bites. For me from early on post-op to now (14 months post op), the full feeling doesn't happen until its too late. By the time I get the "full feeling" its when I have discomfort or indigestion from eating alittle too much. After awhile you become use to certain things and how much you can eat of it WITHOUT going too far. Also, something that happens to me (as well as my mother in law who is about 7yrs post op), our noses start to run when we get to that "full-point".
