When Peaches was diagnosed he had no real signs that I noticed besides weight loss. His regular vet placed him on Humulin N for the next 2 years. I had never heard of home-testing so I just followed the vets advice. He had one coma like episode about 5 months after being diagnosed, which I didn't think he would recover from, but he did. He had been "fine" since. No real problems, just continued taking him to the vet for his monthly glucose curves. I noticed his personality was not the same after being diagnosed, but I figured it was the Diabetes, not the insulin. I know now it was not the Diabetes, but that he was not regulated on N.
