I noticed someone else wondered about the leftover insulin in the vials after filling up pump reservoir 2 or 3 times. I can get two (2) filled reservoirs out of my insulin vial before opening up a new vial. There can be as much as 30 units left in the bottle that I just have to throw away. Seems a terrible waste of an expensive medication. I tried the recyling, taking a syringe and slurping up the excess insulin from one bottle and injecting another bottle with the filled syringe. Nope, somehow this taints the insulin and plays havoc with your blood sugar. I don't know what else I could do and I wonder if anyone has a good but trusted idea.
