The concerns arise more from skepticism about efficacy rather than about
safety.

From a cardiovascular perspective, BG spikes are not as bad as prolonged
periods of modest BG elevations (i.e. fasting BG of 150-200 mg/dL with
max of 250 mg/dL is less optimal than fasting BG of 100-150 mg/dL with
max of 250 mg/dl in the form of transient post-prandial "spikes")

Chris, most physicians understand their role to be that of medical
advisors for patients so that the decision making has been the
responsibility of each respective patient. That is certainly how the
diabetic 2PD-OMER Approach is structured:

Would be more than happy to "glow" and chat about this and other things
like cardiology, diabetes and nutrition that interest those following
