You need to shoot 1.75u for several cycles to see how it works. Lantus is not like Vetsulin, you don't dose based on preshot. You also can't make any judgement about how a dose works after one cycle...the shed has not even adjusted to the change in dose yet. Jumping around on dose will give you wonky numbers. Please stick to the 1.75u for at least 6 cycles unless Smokey earns a decrease.
You need patience and consistent dosing with Lantus. Put the handcuffs on, shoot 1.75u for at least 6 cycles, ok? ;-) The only way I would shoot a different dose is if he earns a decrease.
I know it's hard to see the higher numbers, but you can't use Lantus like this....it's not going to work. You can't chase the numbers. I really do sympathize, but please give the advice you got a chance to work.
