Hi Jacquie,
Remember yesterday when several people told you that you needed more data before you could figure out if 2u was too much or too little? (Nice job getting the mid-cycle test last night, by the way!). Because Lantus is a depot type insulin, it takes a few days for a dose to build up the "shed", so you are just now getting to a point where you can figure out if 2u is right, right? I don't use Lantus, so I really can't advise on dosage.
But, some of the people here have been using it for years, and they've seen hundreds of kitty cases over the time they have been here, so the collective experience here is probably greater than any other single place in the world. To my untrained eye, it looks like Lizzie will need a higher dose. How much higher? Like many people say here.... we don't have crystal balls, so nobody knows for sure. The only safe and logical way to find out what that dose will be is to take baby steps (.25u at a time, .5u at the most).
You may decide to follow the Tight Regulation protocol, or the "Start Low Go Slow" protocol, both are good approaches to treating FD. I guess my point it that the way things are done here has been proven time after time, and kitty after kitty, that they work, and work well. The primary concern on the board is to do things that are the safest possible way to do things for the cats.
I just can't see how, given that the people here have advised that you need more data in order to be able to figure this out, that a vet can tell you "okay, it's time to double the dose and see what happens". That isn't based on any logical or scientific approach to treating feline diabetes. This isn't a race to see how fast Lizzie can go into remission, or become regulated. It seems like your vet thinks it is. "It's a marathon, not a race". Do a board search on that phrase and you'll probably get hundreds of hits. :smile:
I'm glad you found this place when you did. I think what worries me more is that they might hand out that sort of advise to another "bean" at some other time, and put that kitty's life in danger.
Please share all the links you've been given with your vet, for you, for Lizzie, and for any other kitty that gets brought through their clinic's doors.
