I've never thought about sugar level regulation, but am aware of the links between having alcohol and sugar problems. I recently took diabetes blood tests and they came back saying I'm good to go. Would you mind elaborating on what you mentioned?
I am no authority on this, but I have done lots a research on some of these things. Hopefully someone with a deeper understanding will jump in.

A friend of mine has been dealing with sobriety for about 25 years (he is 55 now). He is musician, played in some known grudge bands.....so he is in the realm of excess to say the least. When I met him, he was practically on his way out. He was getting these nasty ulcer sores all over his body, his teeth were falling out. Now mind you, he has never done any opiates. Weed and Alcohol. Mostly Alcohol.
He would come to the house do a bong rip, and watch me prepare food and was amazed at how wholesome my diet is. Whole grain foods, potatoes, yams, lean meats, not much pork....
At the time I was taken herbal medicine classes (Traditional Chinese and western). If he wasn't drinking, he was eating sugar. Through the osmosis of hanging out with me, he started changing his diet. Started a garden (I always have one) and eating better. I looked up herbs that would curb his sugar cravings and he started using cinnamon, making ginger root teas. Long story short, he changed the way he lived and ate. He walked away from the band scene for a while, stop drinking liquors (whiskey, gin, ...). And stuck with crafted beers. He didn't quit drinking, but he curbed it. Some people can do it and some cannot. But he is healthy, happy and maintaining. Now he ferments food, makes his own wine (out of all types of fruits) and sticks with a solid wholesome diet.
You take the American Indians for an example. The sugar they got was from beets. Low glycemic index. And they didn't eat much of it. Then Whitey gave them alcohol and sugar. Boom, down goes the Indian. People think the affects of alcohol would only claim the indian, but it's claimed many of the White, black and any other race.
Hopefully that helps. Let me know what I can do to help. Like I said, there are others lurking who may know more than I.
