What people do not realize when adding insulin, basil or otherwise is that if liver hammers body so hard, the insulin resistance gets turned on hard and that a large charge of insulin will just sit and circulate in body till muscle cells get off loaded of glucose by exercise.
Once I walked the dam glucose readings at 238 in my body down after walking 2 miles down to 140, I would see the injected insulin take off and do its job. i.e. the body can dynamically upgrade and downgrade the insulin receptors of the skeletal muscles based on level of glucose content in skeletal muscles glucose stores.
Science continues to believe in a infinite glucose storage model that does not exist - nor work.
