Lantus is background insulin it isnt normally given more then once a day. Humalog or the like is given as many times a day as needed

When I started Lantus, I was put on the minimum of 10 units and told to increase by 1 every other day until my morning numbers were in range. Well, I got to 80 units with little change in numbers, so I changed my diet and got rid of Lantus completely. Now I'm in range.

get with your doctor on that

When the dose gets higher, like mine at 80, is is more beneficial and effective to split the dose.

When i was in the hospital i took my dose twice a day. But in between that they would give me an extra shot.
