i'll tell you what did it for me to stabilize blood sugar, it was liver cleansing.
it took some time, but a day or two after a good flush eating carbs was a totally different experience and i slowly shifted over to carb based energy burning vs. paleo.
this progressed and i realized one day that i could fast for one or two days with no blood Sugar problems at all. the adrenals do regulate blood sugar, but the core of the issue is the liver's ability to actually store glycogen. once you get that system up and working it is a totally different ballgame.
