| I was on beef/pork NPH & R from 1970 untill 1996 when I was given a pump and put on Humalog.
I have to say, I had no trouble making the switch.
I think all of this is easier understood if we remember that we are all individuals, and as such will all have different reactions to different degrees. Meds, foods, exercise, stress, work. All of our bodies react differently because we are all unique.
Some people have allergies while others don't.......tho I am not suggesting allergies to insulins......I am simply making a point.
It makes sense that some people would have trouble switching, while others don't.
Take care all
