A mate many years ago started working for a construction company and all of the workers were pretty intense gamblers. He ended up gambling non stop, losing his car / girlfriend and in the end his job. Lost track of him after that.
I have found drug addicts to be far worse, their behaviour goes beyond insane when they are out of whatever it is they need. Then after years of taking drugs they are contstantly nuts and cause all kinds of havoc. Actually experiencing someone like this in my life right now
