| I used to take mixed insulin.
I changed because mxied insulin doesn't allow you to have a varied life! To get you BS right all the time with mixed insulin you need to pretty much have a solid routin and eat the same thing all the time (at least the same amount of carbs). It required snacks between meals to avoid hypo's and was generally no use to me.
MDI gives you so much more freedom in what you do, what you eat, whether you eat at all or not. better fasting numbers. The only downfall is more injections... but for me that's not an issue.
After going to MDi i will never look back at mixed insulin... no thank you.
hope that helps?
