I think it was Zoe who talked about free Apidra. Nothing wrong with experimenting with Apidra, esp. of you can get a vial free! And yes, I love my Levemir.
No use in my trying to fight the ins. co. for more Apidra; my doctor already tried. Actually, my doctor and I had to fight to get any Apidra at all rather than Novolog; I'm getting a special dispensation until 2014. My doctor has seen my records with the different types of insulins, beginning with R and N, and fully supports my having Apidra.
I have delayed digestion and poor absorption due to having Pernicious Anemia and Celiac as well as Diabetes, and Apidra's fast onset and short tail work for me. Dinner is the most difficult. I take half the bolus right before dinner and the other half right afterwards.
Good luck with your insulin that had a little time in the freezer.
