welcome to Lantus Land!
I read back through your past threads. I think you are definitely on the right track by testing a bit more. If you are able to get a few more tests in between shots, you'll be able to start seeing some patterns. I usually recommend a before-bed test every night, other spot checks whenever you can (out the door before work or errands, in the door when you get home, and curves on the weekends).
FYI, what usually happens with Lantus kitties is that you work them up to a dose that causes a breakthrough. Then they will often start needing dose reductions. Hannah Belle had a nice breakthrough at 2 units, when her numbers turned pretty much all blue and green. What probably happened after that is that she may have started going low in the middle of the cycles, then bouncing back up before shot time. Because you were only testing at shot time, you assumed that she was staying high all the time, or the numbers were all over the place without logic. I'm guessing that if you had some mid-cycle tests at around that time, you would have seen some lows.
So, moving forward, you caught a 40 and reduced the dose. That's good, and probably what she needed. You'll want to give the new dose a few days to see if she settles into better numbers. Grab whatever spot checks you can between shots, and evaluate from there. Judging from the fast drop from 215 to 107 last night, you might find that she is still going low and might need another dose reduction. Sometimes once a cat starts needing reductions, the reductions can come fast and furious for a little while. Of course that is a good thing for Hannah Belle, but can be overwhelming for you. There are lots of people here who can help.
