Hi Lottadata
I am usin apidra with the pen for 2 weeks now, and love it, not having the risk of posponment of the meal, seen what I will eat, and even after the meal is pretty cool, my numbers are good too

. my pahrmacist told me the lantus can be used for longer than one month, and so far is right, I am using the little container for 3 month, just in case I don't put air inside with the seringe, I keep it at encreasing negative pressure , it's not hard to suck the insuline each time i need it. I hope I can use the apidra for more than one month, do you know about this? when you say you put the pen in the frig, you mean the cardriges, isn't it?
