I definitely have gas, mostly out the top end. I have been taking a gas-x (simethicone) capsule with my daily prenatal vitamin. It helps a little, but I still constantly burp.
I have the supersonic smell, too. Most smells are killing me.
Oh last but not least the hunger, which is fun when paired with the nausea. Today it was more constant hunger, though. Tonight at work, I started craving nacho cheese Doritos, so I bought a bag and then devoured almost half of it. I am going to gain so much weight!
