Hi. I was sleeved 5/8 and I too have pain with every sip I take. It's a pain in my stomach or sleeve now. I have heard that it could be gas bubbles and I took Gas X but it only mildly helped and I have heard for some people it passes after a week or so. I have not once had a feeling of hunger yet. I have had head hunger but not stomach hunger. I am trying to focus on water, protein shakes, and occasional broth, sugar free popsicles, 1/4 cup tomato soup or bean puree diluted. I stopped taking all pain meds and all of my nausea went away. Walking every day a little more is certainly helping. Good luck!
