I don't mind you asking Jethro. She did take metformin and we found out about it through blood work. I can't remember if we asked for her to be tested for that specifically, or it was picked up coincidentally. The only real indicator she had was that she felt increasingly thirsty over some period of time. There was no indication she was prediabetic before the diagnosis, but she did have some diabetes in her family. Have you been tested? Curious why you ask. All the best...Jon
