Hrmmm...I am also only able to take small sips of water at a time, its not painful or anything but I can feel it in my chest. My Dr said that I had to be on liquids for 2 days and then move onto mushies for another 2 days. She also stated that I may have a little discomfort due to the fact that she had to remove all fluid to measure the amount. She said my stomach would swell a little ? :wink:
