I think following SOP(Standard Operating Procedure)-and tweaking the many elements within that to your personal needs is enough to manage. Getting into your Blood Glucose Level, etc is entering a level that is not only unneeded but really just to much to try to manage IMO. Remember “Stupid Simple” is pretty simple. That being said customizing the plan is an option which many of us have taken, and I would strongly recommend. But taking blood samples is taking things a bit to far. Relax, and follow the plan as outlined. Monitor the results, and adjust as needed.
