The "before bed" test is just to get a test right before you go to bed so IF the number is lower than you expect it to be, you can plan on setting some alarms and getting more tests in
The reason I suggested going down to 1.5 and holding it for 3 days is because you skipped the 1.25, 1.5, 1.75 doses when you went straight to 2U so we have no way to know if any of those doses might have been a "best dose" for YOUR cat.
A test I like to get is the +2.....we've found that a lot of times, you can almost use this as a "crystal ball" test.....If the +2 is lower than the Pre-shot, those are the cycles you want to get more tests in because kitty may be making a move down during that cycle and you need to find out how far down they do.
If the +2 is about the same as the Pre-test, that usually means a more normal Lantus cycle that gradually goes down to nadir and then gradually goes back up to the next shot time.
If the +2 is higher than the PS, that can signal the beginnings of a bounce...and on those nights, it's safer to take a pokey break and catch up on your sleep!
Lantus dosing is based on how LOW it takes them, not the pre-shot numbers, so getting those tests in will really help to figure out what's going on
