Here is the best
link that I can find, which pretty much describes what I have experienced. In a nut shell, one or two is probably OK, just treat it like food, excess drinking will cause the blood glucose level to go very low. I hope the information helps.
On a side note: I don't think that it is the Tennessee sour mash. It couldn't be, I live in the bourbon and whiskey capital of the world. I am right in the middle of Jack Daniels and Wild Turkey.
