thanks bsc! for all this information. I'm going to read all of it.
I still have one of the novolog pens half full, I think I may try it again, I have a feeling from something someone wrote in Clare's post that it was my lantus that may have not been working.
I pay a copay only too but it's not cheap and I guess I feel bad to waste something like this. I don't do the clearing out of 1-2 units except when I'm starting the pen/pen refill so I guess I'm using even less that way too. You're right though it's not a good idea to use half good insulin of course.
I was reading about one insulin, maybe humalog- I can't remember now, that lasts for 45 days, but I'm not sure if that one would be right for me, so I think transferring half of my 300 ml refill to an empty vial and storing that in the fridge might work for me.
I guess with syringes you don't waste as much maybe and you can get a smaller dose for corrections which I would prefer, but I really prefer pens overall- I only did the syringe once in the hospital when they were showing me how to do it and I had a hard time with it since the needle is longer and it was very awkward.
