Insulin isn't all bad Molly. The way he was going was likely to cause retinopathy with his eyes longterm and if that can be avoided by lowering the BG results the better. He will not like having to test frequently or every time he gets behind the wheel. However, he would lose his license anyway if he lost his sight, so a few tests isn't the end of the world to keep his license.
Has OH had his eyes tested Molly? He could be better persuaded if he thinks he could be liable with unstable bloods, which he currently has which could cause him to have eye sight problems.
I was just reminded of this, because I had all my eye tests done today and yay, I'm singing... No retinopathy, perfect pressure and peripheral. Optician said I was her best Longterm T1 diagnosed patient..... Yyyyyyaaaaayyyyyy!!!!!
However, Molly. Good that he went, blood pressure ok etc... Considering the holiday, results could have been worse, so your attempts to bring lower carbs in to diet has staved off a higher bg, which could have happened... I know he not perfect with his eating, but he would have been horrendous if you not around.
So insulin not the end of the world, although he will have to carb count then too unless he goes on to a mixed insulin where it is slightly less necessary according to the DSN,s....
