Hi everyone, As a follow-on from another thread, I am fairly convinced that I need to look at changing the type of insulin we are using for Abby. We have been working for a few months to get her BG regulated on vetsulin. Please see my spreadsheet in my signature, and in particular the chart of her curves at the bottom of it. For a while there we had gotten her down to a nice gentle curve (green and yellow lines) which just needed to be shifted downward. But as I continue to increase her dose slowly, instead of the curve shifting down, it just kind of stretches, meaning the nadir gets lower but both ends get higher. You can see this on the chart. Also, possibly related is that Abby is experiencing some severe behavioral issues which seem to have started not when she was diagnosed with the diabetes, but instead after we started her on this insulin. I am going to the vet for a pre-scheduled appointment on 5 Aug and I'll be bringing my spreadsheet in hopes of my vet maybe being willing to try something different. However I'd like to get myself better educated before we go. Based on Abby's curves, is there a particular type of insulin that might be good to try next? Do her curves indicate vetsulin is too short-acting for her, or something different? Are there significant cost differences that I should be aware of? Thanks so much, as always, for everyone's help!
