My Novolog experience was a faster and slightly sharper peak and I never have been able to figure out the tail effectively. All of the insulins seem to act differently for everyone. While I am a Humalog user, I keep a backup Novolog prescription on file with a local pharmacy because I have tile floors in my kitchen where I store my insulin and I buy via mail-order. Oh - and I'm a bit of a klutz! Nothing worse than no local prescription in an emergency... ;)
Where the coverage is concerned - make sure you don't have a ceiling on your maximum out of pocket for prescriptions before costs change - I think I have seen this on some policies a lifetime or two ago..
I was forced into the mail-order switch because Humalog is about 50% more expensive but I get one month free of the 3 month supply when I buy through the mail.
My coworker just switched to Apidra and he loves it. I hear it is more expensive...
Hmmm - well, I typed a lot and I'm not sure I said much of anything that helps :(
