Deaths belonging to alcohol happen from time to time, but the chance to actually die from is very small i guess.. If you really want to die from alcohol it'll be a long way with a bitter and painful ending. Alcohol causes so much diseases physical and psychological (i.e. liver failure, pancreatitis, high blood pressure, poly neuropathics, wernicke encephalopathie and korsakow-syndrome, etc.) And i left the addiction and the withdrawal out of the equation.
Try it, but you'll only have the hangover of your live. Why don't choose another method ? SN, SA, gun/firearm, ... ?
