My indicator is that the more food I eat the more my nose runs. Gross? Yes. True though. And my telltale sign? A hiccup. Even if I have eaten too fast and don't feel full yet, my body will hiccup when it's had enough. Sometimes I don't feel full, but realize that proportionally I should be done...so I wait. I wait for the inevitable hiccup. It comes! It always does!
It's funny how God wires us, isn't it? And then when we re-wire our bodies through RNY, He still uses His design to speak to us. I still struggle with listening some days, but I am thankful I've been able to figure out this signal.
So, what's your sign?
