Hi there, firstly happy new year everyone. I have been using Humulin M3 KwikPen 32 Units twice daily, before I used Humulin I KwikPen 28 units twice daily. My blodd sugars are coming out in double figures like 22.4, 15.6 and so on. I spoke to my DSN yesterday on the phone and she thinks I might now be insulin resistant. She wants me to go see her this Thursday as she wants to get me started on a stronger insulin. Can anyone tell me what the stronger insulins are please ?
