Finally I have taken matters into my own hands.
I am now taking a combination of Humalog for short acting insulin and NPH for long acting insulin.
I am so happy with this combination. I take 10 units of NPH morning and 10 at night. I've never had a low with this basal level. My fasting levels are now in the 80s.
I am guestimating still how to much humalog - and not testing very frequently (fortunately I am very sensitive to going low and can feel it well in advance). So I've started with a ration of 10:1 for breakfast and lunch and 15:1 for dinner. If I don't eat carbs I don't take any. So far my highest detected no. is 126 at 1 hour post eating. I haven't had any lows.
I am so happy with this now. I can eat what and when I want!! So much freedom compared to just using the 70/30.
Don't know what my doctor is going to say when I confess. But I swear I don't want to go back to being forced to eat on a schedule with highs and lows.
Issue is that I am trying to get pregnant again, and my doctor says nothing is safe except the NPH.
I do have some insulin production of my own. So hopefully with this approach I will keep that forever.
