I believe someone mentioned in a previous post that their d-son's doctor had them use a different insulin to bring numbers down (i.e. if using Novalog switch to Humalog or Apridra to get the numbers down as the body recognizes the new insulin). Is there anything to this? If so, we should all have a spare bottle of other insulin on hand for illness/insulin resistance. This is especially timely with the stomach flu, H1N1, etc. raging.
