Nearly 80 hours. This was around 12 years ago, I had a full time job and was on a volunteer fire department. I would get off work and immediately get toned out for a fire or back to back medical calls until my shift the next day. It took copious amounts of caffeine to keep going, and eventually I just crashed out from exhaustion. 0/10 don't recommend.

We're better together. Don't try to survive on your own, having friends you can trust is crucial for survival
