I also had my surgery on January 23 and I have the pains all the time. It is definitely gas. I hope it is temporary. I would hate to think it would always be this way. So far all of the liquids I have tried have agreed with with and just today I discovered Dannon Light and Fit Greek Yogurt with 12 g of protein and only 7 g of sugar so I blended it with 8 oz of 1% milk for an awesome 20 g Of Protein drink that tastes better than the Boost Glucose Control I've been drinking. I am looking forward to February 1 when I add puréed carrots, butternut squash and sweet potato. ????. Pat
