Founded a startup, worked for 1 year 10-14 hours per day, incluing 5-6 hours saturdays and sundays. After 12 months, I started to wake up dizzy in the morning, and having spontaneous nausea during the day. General feeling of wanting to die all the time. We decided to shut down the start-up (unrelated to burnout), and the disappointment made me to develop an "allergy" to working. My brain would stop functioning in front of my computer (very weird). I had to stop for a while, wind down hours, and it took me A WHOLE YEAR to get back to feeling good again and being at full performance again. Had to go back to doing sports, some meditation and deep spiritual introspection. I must add: I believe burnout has more to do with stress and nervousness and being pessimistic about the outcome than the sheer amount of hours. If you are super excited and happy with what you are doing, it's less likely you'll burnout.
