He's getting there. You've a couple more days to go on this dose if you're going to follow the Start Low, Go Slow protocol.
If you want to step a touch faster at first, once you are at 5 full days on this first Lantus dose, if the nadirs are still high, you may increase 0.25 (we eyeball quarter units). As you get closer to control, unless you're able to monitor a lot, the SLGS protocol will be safer.
