So it would be ok to shoot his whole dose at 150 if I’m around to test a few times? Sorry, just seeing this now.
You really do need to start shooting anything over 150...
as long as you can test, you are in control of his blood glucose. As you gain more experience and confidence, you'll actually start shooting even lower numbers. I would shoot China if she was above 50 (on Tight Regulation) and you'll need to learn to shoot Prince if he's above 90 (SLGS)
Lantus works best when it's given at those lower numbers. I know it seems like if you gave 1U when he was at 300 and he dropped to 150, that if you gave 1U at 150, he'd drop to zero, but it doesn't work that way!
