Ever since this thing has started up, I don't eat as much, and when I am hungry and go get something to eat, all of a sudden I don't feel like eating anymore. Also when I'm hungry, I'll drink first, and that fills me up, or a small cup of something to drink, and about 3 ot 5 bites of something and I'm full. I don't eat like I used to, and when I try to eat like I use to, I get sick because I ate to much. Is this a problem?
