I am on my second week of "mushy" foods and I have two distinct signs, 1) the hiccup or burp. I will hiccup hard twice quickly. That is my que to stop. 2) just before the hiccup, almost as a pre-warning, my nose will start to run. I can't explain it, but I have learned quickly to listen to my body. When I was on liquids, I had no problems getting 60-80 g of Protein by basically sipping Protein drinks all day and I never really ever felt "full". As soon as I started the mushy foods, a few bites in I would start to get that feeling. 3-4 Tablespoons of food really does fill you up! Good luck!!
