in the last few weeks, I have been holding the dose for at least 5 days. Before that, i've been playing with the dose too often, but I am learning to shot low to stay low, and some other things. And this TR method, I am getting used to it, but it takes time . You say I should hold when green, but then it goes back to high numbers, especially in the evenings. When and how do I know it's time to increase ?I agree your cat bounces from being under 100. There is no evidence that Somogyi exists in cats. That usually stops if a cat surfs in better bg. You are increasing too often. You want to hold a dose for at least 3-5 days before increasing. Once you start seeing green hold at least 5 and see what happens. Some cats take that long to see what a dose does for a cat.
