For about 3 years, I did 12 hour days (4 hour sleep sessions) and inverted days (go to sleep at 7am, wake up at 3pm). The benefits outlined in the article were definitely there - Life felt less busy, and I had a new perspective on everything - But I got sick often, and doing a hard reversal to accommodate visiting family or friends on weekends was brutal (I fell asleep multiple times at houses when I was supposed to be "hanging out"). Overall - I don't regret it, and if you're someone who likes to try different life experiences, give it a shot! But I'm not going back anytime soon :)
