But it does make the picture clearer. The 5 units looked pretty good, giving him a 276 at +4. The ten units look like too much to me - dropping from HI to 125 is a huge drop.
Why aren't you giving insulin tonight? I wouldn't think you'd want him HI until tomorrow am.
If he were mine, I would try 5 units twice daily and see if that gets you some good midcycle numbers.
