damn that really sucks scoob. sounds like you were a good friend to him. its tough watching someone hit rock bottom.
i have a friend that had his wife divorce him, dad died, and got laid off from a job all within a 1-2 year time span. dude started drinking every day, wouldn't apply for jobs, etc...he was jobless for 3 years, i guess his mom was supporting him. he then got his act together, stopped drinking and went vegan for a year - lost a ton of weight...and got a job. now he's back to eating meat, hitting up the booze hardcore again, gained all the weight (plus more) back. we have all tried to intervene, but there is only so much you can do. i have a feeling he is going to end up like mofo.
