I definately agree that it is probably the rice. Try eating shashimi (is that how you spell it) instead. I definately have trouble eating rice, bread, meats that are dry and not soft, cereals that are bulky. Went to Hometown Buffet Sat for my daughters birthday. Had some baked squash that was soft and right after ate a piece of chicken breast. Everything got stuck. I knew I was in trouble. Calmly walked to the bathroom and knew that I needed to start running. Just made it to the bathroom and everything came up. What surprised me was that the squash came up pretty quickly even tho it was soft. I guess you never know hau? Its really all about experimentation. Good luck.
