I didnt think one could do it but you can drink yourself to death. I knew a shy soft spoken dude who was an ace bike mechanic and even worked for a factory race team. He got himself into a bind with a woman and had a child and he could not take the situation he found himself in. He pretty much took a year of hard alcohol daily which pickeled his internals so much so that his body shut down. There is much more to the story. This dude is just yet another human who slow motion suicided.
