Just a housekeeping note.....each day when you start a new thread, you should put the link to your previous thread in so it's easy for people to go back and see what's been going on.
Here's the
link to your previous thread
One thing I do notice is that you've changed his dose several times lately. Lantus craves consistency, so we need to find a dose that you're comfortable giving both AM and PM. Each time you change the dose, you disrupt the depot so you end up with wonky numbers.
The fact that he's going up so quickly tells me it's probably going to be safe to go ahead and give the same dose (which is why I asked if you could monitor him as long as necessary tonight)
If it really concerns you, you could always shoot a slightly reduced dose, but we do need to start being consistent with the dose or we're never going to really know how he's doing.
Would you feel better about giving something like 7U and holding that dose for at least 3 days?
