Bhooma gave you the link to the information on dosing strategies that we use. I'd add a bit to her comments. With either method, you need to test a minimum of 4 times a day -- at your pre-shot times and at least once during each cycle. Many of us who follow(ed) TR test a lot more. In my case, I tested a lot because I had a cat who was prone to large, fast drops early in the cycle and because I like having data. It was a personal choice. There are also members who use SLGS who test a great deal. And these days, with the continuous glucose monitors like the Libre, people will post data from a 24 hour period since the monitor records the information automatically. (There are trade offs with using the Libre or other similar monitors.)
I would encourage you to get your spreadsheet set up and linked to your signature. We are really not able to offer much guidance without the results of your testing. Just like we discourage shooting blind, we discourage giving feedback without seeing the data. I can open your spreadsheet but honestly, I don't know what criteria the FDSG uses for dosing. Bhooma can help you if you need a hand with using our spreadsheet. This is the link to our post on
helping us to help you which includes spreadsheet and signature instructions.
I suspect that there are many people here who empathize with you when it comes to whether or not to listen to your vet. There are absolutely any number of topics where a vet is more knowledgeable than we are. Feline diabetes may not be one of those topics. This message board has been around for 25+ years. We have an admirable record of getting diabetic cats into remission and for keeping cats safe. We do our best to stay on top of the literature -- several of us have access to veterinary and medical libraries. The primary difference is that all we focus on is feline diabetes. Vets have to treat a wide range of conditions and in many cases, treat those conditions across a variety of species. As an example, the Tight Regulation Protocol, which is the published method for treating feline diabetes with Lantus (and Levemir), specifies that dose changes (in most cases) are done in 0.25u increments.
The good news is that your vet didn't yell at you for listening to a bunch of "crazy cat ladies."
