maybe you aren't eating more than what they think is normal but if your stomach is smaller or has shrunk then you might not be able to eat more than you are used to. if you suddenly can't eat as much as you could however you might have another problem that needs a doctor. for now maybe you just have a more sensitive stomach. maybe it's the irritation from the heartburn.
i vomit after having a meal that is beyond the way i used to. but they are telling me that i did not ate too much. why? . when i ate that is greater than i was used to i vomit. but people around me keep on saying that you've not eaten that much. previously i had a heartburn.
