Wait, test again to see if he continues to go up and shoot your normal dose if you are going to be home today to test. You'll want to keep trying to get him to eat as he didn't get his shot yesterday and the resulting numbers are so high.
May I ask please, why are you giving Lantus at such a variety of times? Work issue? Lantus really needs a very consistent daily/time schedule to work best. Early or late dosing can 'appear' as an increase or a decrease.
