I've been doing the SLGS for now. His numbers were so weird on Prozinc that I want to see if they are leveling or curving better overall. He seems to be getting more regular now that he's on Lantus. If you compare the spreadsheet numbers from Prozinc to his numbers now on Lantus, it looked like a random number generator was creating the data on Prozinc, but I'm able to see curves and patterns with Lantus.
I did a .25 increase after 9 days and a curve. His numbers look even better now. I think this is the insulin for him for sure.
