I feel you! It's almost like torture to me to watch everyone else enjoying food. I try to tell myself it will all be worth it, but I know how you feel. I am only 13 days out.
I also started pureed food this week. I made chicken salad and put it in the food processor. It's not totally pureed, but it is close. When I eat it I get some pain like I need to belch. I'm wondering if I am eating it too fast. I am paranoid about leaks, but I am not having any other issues.
