You're doing a good job testing and increasing safely. The +2 is usually a good indicator of how the cycle might go per the chart below which is found in the
The Basics New To the Group Sticky . I don't think you're over testing but every hour is not necessary unless she is in low numbers. Nadirs to move around quite a bit and that is normal.
Example of an ACTIVE, but NOT necessarily typical Lantus cycle:
NOTE: Until kitty is pretty well regulated, the description below is
NOT not what you'd consider a "typical" Lantus cycle. It takes time and patience for kitty to achieve a "typical" cycle! The example below is what you're working towards (a nice shallow curve). A relatively flat cycle is the ultimate goal.
+0 - PreShot number.
+1 - Usually higher than PreShot number because of the last shot wearing off. May see a food spike in this number.
+2 - Often similar to the PreShot number. Onset begins around +2 for most cats. You'll probably see an active cycle if the +2 is the same/similar OR lower than the preshot number.
Continue testing!
+3 - Often lower than the PreShot number.
+4 - Lower.
+5 - Lower.
+6 - Nadir/Peak (the lowest number of cycle. NOTE: ECID. Not every cat has a mid-cycle nadir. Adjust the hours on this example to fit your cat.)
+7 - Surf (hang around the nadir number).
+8 - Slight rise.
+9 - Slight rise.
+10 - Rising.
+11 - Rising (one of the quirks of Lantus/Levemir: some cat's blood glucose numbers dip around +10 or +11... not to be confused with nadir).
+12 - PreShot number.
