I was hoping someone could help me with this problem. I've been feeling light-headed after meals this past week. This hasn't ever happened before, but I was told that I needed to gain weight so i've been eating more often than usual. It just seems like after every meal, I feel light headed and sometimes even vomit because I feel so bad. Can anyone tell me why this is happening? Is there something more I can do to make sure I don't get sick after eating? Throwing up kind of defeats the purpose of eating in the first place, right...? Any help would be appreciated. Thanks.
