Labas Ruta,
I do not think you need to give up. I have not been around last week, because I had to go into the emergency at the hospital--bad heart. I looked at Cupcake`s numbers and you are doing better, but I think you are popping around with your doses too much. As I have said I do not know lantus, but I am sure that Mel or someone who knows will give you guidance soon, and I think you will be okay to wait if you are unsure. Now that Cupcake is off his antibiotics, he will possibly need less insulin. As well I know it is hard to not react to that one high number but you should try to not change his insulin shot so much. My husband is diabetic--also diet controlled-- but he says that too high feels the same way as too low does, neither particularly good. I am sure that soon you will see less variance in Cupcake`s numbers.
