I get the impression from reading Dr Bernstein that we diabetics should keep to a cast-iron timetable of the utmost regularity. Same amount of food containing same amount of carbs & protein at the same (far apart) intervals. IMO on top of our having to give up everything not on his "allowed" list, this is a bit much. I'm not sure I'll ever be able to live my life with such admirable regularity, control and predictability. A robot might do better! But maybe that is what it takes to have no spikes or lows, which would indisputably be the best for our health.
My understanding of Metformin is that it stops the liver dumping glucose in to the blood. Does this mean that we don't get a boost of glucose when we actually need it, as the price for not getting rogue boosts when we don't, as in the dawn phenomenon?
