| I had problems with Levemir also - I thought that maybe it had frozen in my fridge, after a couple of days with abnormal highs I went to the pharmacy and got a new pen cartridge. With the new insulin, I was back to normal.
I also never had bad insulin with other insulins. Thankfully I didn't use Levemir very long - my work's insurance approved a pump for me and I'm now on Novorapid using that.
