Thank you all for your replies. It is interesting how opinions differ. His current Lantus dose is 25, and the GP said up it to 30, even as high as 40, before he sees the consultant next week. I just feel even 5 is a massive jump - being scared of night-time hypos, so going up 15 seems suicidal. I guess though, given that his waking levels have been as high as 14 (when he last tested a month ago) that he actually will probably be fine.
I am very scared to hike it so much given that the GP admits diabetes 'isn't his thing' - he's a dermatologist by specialty - and I really do think he is out of his depth to some degree. Saying that, he is incredibly thorough and doesn't like to leave any stone unturned. I just feel happier leaving things until next week, or at least only making minor changes.
My son was very subdued this morning, but I did find more used needles than usual in his room this morning (he is an incredibly untidy so-and-so and leaves used needles on his desk - but at least I get to see how many he has used) so I hope that means he had some novorapid last night, and again this morning. I asked him if he upped his Lantus last night, I got the bog standard reply - 'I can't remember!' I left it at that. When he came in this afternoon he went to his room as usual. I told him units for dinner, but whether he has had any or not I don't know. I actually suspect he hasn't as his backpack has sat on the bottom of the stairs all evening and his kit is kept in there, and he always takes it to his room. Some time later he came down and something was said again, so I just asked casually again 'So how many units of Lantus did you really have last night'. He said 28, but he said he has been gradually been increasing it lately anyway. I don't have a clue if he has been testing though to see what effect it has had.
I can't remember who asked, but no, he is not seen in adults yet, he is seen at the children's hospital - don't have a clue when he will be moved over to adult services - it has never been mentioned. Is there a standard age they are moved? Or does it depend on things like age at diagnosis? He is almost 17 now. He is currently seen there every 3 months. Will that change under adult services? I suspect yes. I quite expect though (from a friend locally whose son is also type 1) that they may want him back within the month with levels like this. We should have had a home visit end Oct/early Nov from our DSN and dietician, but for whatever reason it never came about.
Back to the Lantus, I am just so wary that at the start the nurses were so strict about the altering of the dose of that. They said he must never go up or down my more than a maximum of 2u at a time, preferably only one at a time. I think he started initially on 30, then came down bit by bit to 25, which is where he has been since about his third week.
He is more just plain old bad tempered tonight, pretty much aimed at me, but I am big enough and old enough to handle that! His sister will be home from uni at the weekend and they do get on very well together, and she has a great desire to chat to him one to one, so maybe she can get somewhere with him.
I just want to say a massive THANK YOU to everyone on here though. I really value having people to talk to. I love my husband dearly, but he just seems disinterested and gets bored when I want to talk about things. He just doesn't seem interested. Men eh??? (Sorry boys on here, you lot are great)

It's good to be able to share my worries and thoughts though.
I will keep you all posted with developments. Watch this space.....!
Oh and we do possess the Ragnar Hanas book, but again he isn't interested. He says he can't understand why I bought it as it's not my problem, and though he did a token flick through on one occaion, he hasn't touched it since. I may mention looking at it again, or pop it into his room, but I know I will get a knock back from him.
