Definatley mention it your DB nurse and do not be fobbed off, if the only thing in your life to have changed is your diabetes and you were OK before, then you have to look at what you have changed, daft things like cutting back on coffee etc. can make a big change to how you feel but if you have not drastically changed anything you need to look at other things.
You say your BG levels are good so that should not affect you, I know when I am high my mood changes and I know when I am low my mood changes. But I recognise those as being high or low. But the Iratibility is something totally different.
Its hard to explain it, pretty much like when someone is deliberatley winding you up and you can feel yourself getting less tolerant. The Lantus definatley had that affect on me and the levimir has not been as bad, but I was telling my wife about your post and she says I have been really irratable for the last week since starting on the leveimir :shock: The other thing it does, is make me itch, I want to keep scratching my arms and my face, usually within an hour of taking it, then it gradually wears off.
If you look at the forum you will see a lot of people don't get on with certain types of insulin, until I started reading the forum I had no idea that Lantus could cause so many of the symptoms I was living with. Which is why I recently changed to Levimir. I have an appointment with specialist in November and I am going to see about changing to something else.
As you are new to the diabetes game, it could well be you are just having to adjust to the whole way of life and deal with the changes your body makes. But if you feel how I think you are saying you feel, its more than that. OK so you might need to change insulin but its better to go through the hassle of changing insulin than to risk your relationship etc.
Good luck. :mrgreen:
