Oops - I seem to have opened a right can of worms here! Thanks Catherine for all the information, I was actually aware of all that. I downloaded the diabetes form months ago when he talked about it before. I agree with you, all it emphasizes is hypo awareness, not high levels. I have trawled various documents about driving and type 1, and nowhere have I seen anything about high levels being prohibitive, nor have I seen anywhere that you have to prove yourself by showing 3 months worth of BG readings. That's not to say I would be happy him driving in his current state though. I did mention to his old DSN a while ago about driving, and she said it's all about hypo awareness, so I really don't know that he would have to produce his meter readings at any point. I have certainly never heard or read than anywhere before.
I did also point out to him the box about testing before driving and every 2 hours thereafter, and did point out he is signing a declaration which could be produced in court if he did have an accident. He intends using my daughters old driving instructor. He is a T2, so I plan to have a word with him on the quiet first asking him to tell my son he HAS to see his meter EVERY time before he gets behind the wheel of the car. If I ask if he has tested before going, he is bound to say yes even if he hasn't. If his instructor insists he sees the evidence, he can't get away with it the same. He can then be the bad guy, not me!
I did email his old DSN as I have no contact details for his new one, and just ran by her what happened and asked if I should have done anything differently. She said she wouldn't normally advise giving any insulin to someone who was drunk, but given his BG levels it was the right call and if it were ever to happen again, I could go as high as 8u of Novorapid with a BG reading over 30. Hopefully that's a piece of information I can just file away though and never need to use.
She has suggested I try and talk to him about not using his Lantus, as she said that would have made things far less serious. He hasn't used any for at least 3 weeks that I am aware of. She has suggested that if it is due to him being scared of going too low they could reduce his dose and then build it up bit by bit. I personally think any amount of Lantus would be better than the zero amount he is having at the moment. He should be on something like 28 or 30 units. The lowest he has ever been on is 25, so maybe start there. The problem is they have upped and upped his morning M3 as that seems to be the only one he is using reasonably regularly (still skips an odd day or two here and there), so I guess the slow acting bit and the Lantus were overlapping and that was causing him to get a bit low now and then. The trouble is he has gone back to being Mr Angry again now so I have backed right off. It will be counter-productive at the moment. I think I am going to have to leave it a good few days before mentioning anything again. His new DSN is due to phone him one evening this week, maybe she can get through to him a bit. Next clinic mid October.
