I have noticed that if I take to large of a sip or drink to much at once that it does cause pain.  Right under my breatbone in the center.  Also if I sip to fast I burp alot.  Have been trying to start adding in some protein mixes.  I have one that is like Hawian Punch and is really good.  Has 15 gms of protein.  Not felt hungry and luckly have not had any nausea thus far. 

Well I had RNY and a little bit different situation but because of the swelling after surgery nothing was passing through my pouch. So they had to put a tube down my nose into my pouch to suck out everything going in so I was not sick. Then when the swelling went down everything started passing and they could take the tube out and i could have fluids other than ice chips!! Good luck to ya!! It'll get better!! :)

I had hiccups to. I don't think it's drinking too fast, I think it's just the liquid going through the pipes. Lol

Wow you are doing seriously Good. I almost wish now I had to do an extra week of liquids

Thats AWESOME! CONGRATULATIONS!!!!
