Is Humulin I the best type of insulin to use for Basal? I am newly diagnosed type 1. Was started on mixed insulin Humulin M3 and after struggling to control highs and lows and advice given on this forum I asked to move to Basal Bolus regimen. The nurse has started me on Humulin I only, twice a day, and said the Bolus will come later. She wants to get the Basal dose right first. When I have looked up Basal insulin I think Humulin I is an NPH insulin and may not be the recommended type? If so why would the nurse start me on it? I am not due to speak to her again until next week. Thanks for any insight
