I have not, but lots of friends have. They often went through giving up everything nonessential – which varies by person. Some see doing without manicures or a cell phone as a hardship (at least at first), and a couple of my friends decided to live outside or in the homeless shelter. For most friends, they had some kind of reserve of savings, and unemployment to draw upon, but others didn’t and had to couch surf for months. The thing is, often people don’t manage to “take care of everything.” The parts of ‘everything’ that you decide not to take care of often determine how long and how well you will be able to manage the rest. Some people don’t make it. Your friend sounds lucky if he is still (barely) making it. I wish the best for your friend.
