Hi,
I'm awake. I'm in Belgium, so it's 10am here already. I'm quite new to all this, so I am not much good in the advice department, but my Suzie has had those sort of scary high numbers and toughed her way through it.
I'm assuming Jane eats when she has lower values, so even if she does not feel so well during the high ones, she has strength to get through it. I have also learned to be careful about giving shots with Lantus between the 12 hour shots as it is has a delayed reaction, and I wouldn't do it without advice from someone very experienced. You are doing the right thing.
Sorry I cannot be of much help, but I thought I'd pipe up and offer moral support since I happen to be awake when much of the board is sleeping. I'm sure that as soon as someone knowledgeable about doses wakes up, they'll give you some good advice.
Hang in there !
Maria & Suzie
