My son is recently diagnosed. He is honeymooning so his ratio is 1/2 unit:20 carbs. When he was first diagnosed, they started him on humalog and lantus, but we took him off the lantus due to lows during the night. His numbers during the night have been creeping back up lately (around 150) so I tried 1/2 unit of lantus again and of course, his number went down to 65 during the night. Lantus just scares me to death because I never know what its going to do when. Any suggestions?
