Wife and I ate at TGI Friday's. Both carb counted. Four hours later I had a sever low. Almost passed out. Ate around 8pm. Low at 12:15. We are nite-owls. Type-1 for 20 years. Pumping with Medtronic 722 for 9 months. I don't understand this. The insulin would have worn off by now. Anyone ever have this problem?
