That's because alcohol has high levels of sugar. When we drink, our body says "too much sugar" and dumps our storage, therefore causing hypoglycemia. When I was drinking, I had INTENSE problems with food, couldn't eat food high in carbs or sugar unless I had a lot of protein to follow it. My heart would raise, hands would shake, dry mouth, headache, etc etc etc. A week into sobriety the problem vanished. Took the alcohol away and away went the hypoglycemia. A lot of alcoholics are looking at this latest study as a cure all to their alcoholism. Fix the hypoglycemia and I can drink normally? No. Quit drinking and fix the hypoglycemia. If you fixed the hypoglycemia and I picked up a beer, before you knew I'd finish a 12 pack and God only knows what would happen next. I mere sugar problem would not stop the obsession to drink. It's not the cure. That's my humble and scientific opinion.
