I have to take my levimir in 2 doses...one before breakfast and one before bed. It works for me, and isn't as stingy as lantus. If the disposable pen is working though...fantastic! I can imagine that the thought of another injection might horrify her, but as far as I am aware, most people on lvimir take it twice a day...I moved onto it in the first olace becasue my lantus "ran out"...so it must be something to do with how quickly the body processes the insulin.
As for the hypo thing..poor girl. I hope that they can help her. If it helps, to me, hypos, in the early stages are just like getting a bit drunk! My head goes a bit funny, and my brain slows down...but just like getting drunk, if you stop the hypo, or drinking at that stage, it soon passes, and no real harm is done. Obviously, serious hypos are worse than this, but a hypo where you need someone elses assistance, is rare. It is frightening and embarrassing, but shouldn't be life threatening.
It is difficult to write this in the right "tone". I am trying to reassure her, without belittling her fears. They are understandable, and common...having a concerned and caring Mum has got to help too
