To keep this simple, my son was getting Lantus at night. More than 2 units made him tend to go low and 2 units didn't seem to help much past lunch. He would rise late after lunch and dinner before his night time shot. Tried 2-3 alone in the morning, but then he rose during the night out of range. So I tried splitting it, but ran into this problem: The morning (7:30) dose of 2-3 units seemed to work until around midnight, not sure but somewhere between 10 pm and 2 am before it ran out. The night (7:30) 1-2 units PEAKED around midnight and now was overlapping with the morning dose, so giving a larger morning dose actually gave him the highest basal in the middle of the night when he needs it the least. So I was wondering if people had strategies to work with Lantus that worked for them when it didn't seem to work the full 24 hours? Anyone try splitting it but not 12 hours apart, or unevenly like 60% and 40%. Basically he needs more in the day and less at night.
