T-7 Stomach feels odd

Good Morning all

Well its offfically one week away! I can't believe it myself. I have so much to do before the big day, i guess I better get busy, but its been a little hard considering I don't have much energy. I'm still losing 2 pounds per day (down 12) but I noticed I am no longer hungry. I don't rely on the raw veggies as much, if at all. My stomach however does feel as if it weighs a brick whcih is odd since there's no food in it all. Has anyone else felth like this? What should I do? Also I'm belching all the time. I had hiccups yesterday, but now i'm just belching. Perhaps my stomach is empty??
