Beltar: "Nasty like fat calories"? What is this, 1992?
Anyway, alcohol is actually a sugar, nothing like a fat. There's a few alcohol sugars, just like normal sugars: sorbitol/glucitol, and mannitol (and some other one that starts with x). These correspond to fructose and glucose etc. although to be honest I don't know which ones are heavily present in most drinks. Most of the alcohol sugars are converted into fructose in the liver, so drinking would be most like ingesting a ridiculous amount of fructose in a night. JB must not drink that much.
So, for damage control I try to limit my fat intake (heh, massive eating compliant drinking binges), and eat some healthy fibrous carbs before bed with a BIG badass protein shake. Oh, and rehydrate like crazy.
Works for me, I rarely get hung over.
