Does anyone else get uncomfortably full after drinking too much fluids? I tend to have this problem when I drink any kind of soda. Today I had half a cherry coke, half a diet coke, and half a caffeine free coke... I feel very full and bloated. To top it off the soda made me extremely thirsty so I gulped down a water bottle. Now my stomach is super full and I can feel the liquid moving in my belly when I lay or sit. It's a very uncomfortable feeling and I tend to only get it when I drink soda. I barely drink it and this was the first time in weeks that I had this much! What is it about soda that makes the stomach so full? My fiance can drink gallons of diet coke and not feel full at all, but just 3-4 sips makes me feel like I ate a whole meal! Is this normal?
