I wonder about that, carb addiction. My BFF since we were 3yo is an alcoholic. She has stopped drinking but is now making fruit shakes, eating lots of sugar like cookies and ice cream instead of eating real food. I think what she was doing through the years instead of eating dinner after work, she was drinking her dinner every night which morphed into day and night, although she was always a functional alcoholic.

Once when I was visiting her and I cooked dinner and had it ready when she got back from work. I could tell she was annoied because I think I had infringed on the drinking by making food.

I have thought about this a great deal and after she recovered I told her that I thought she was drinking her dinner every night. I now think it could be the carbs in the alcohol that drives the urge to drink, not necessarily only the alcohol, although I could be wrong.
