Eunice!
Hey, well from my sister she only had diet soda sometimes. No caffine, its not too good. No prescription drug of any kind is good. You should ask your doc on that for alternatives if you taking something. About the hunger, I knew a girl who lost 6 pounds before she started gaining it again. My sister didnt decrease her appitite but she gained a big one! Hahaha she never said anything about her stomach feeling funny other than it was growing a little bit. And when the baby kicked it hurt like a twitch in your body. You should ask your doc about all these things and they have magazines and brochures and stuff like that on babies, what to eat, what not to eat. What to do, what not to do. Things like that.
