About 48 hours. I did a 100km team charity walk that took about 30 hours, I woke up early and anxiously before it, and was too wired on caffeine to fall asleep easily afterwards.
4 days awake. Worst tooth infection ever… my head was basically exploding. Swishing cold water would kill the pain for about a minute. In retrospect I should have went to emerge? I’d lay down and start to fall asleep, then BOOM. I was starting to have hallucinations and I think I was seeing “shadow people” out of my peripheral vision. Eventually the antibiotics kicked in and I stayed asleep for 5-6 hours… something woke me up and I bolted awake… I WAS ASLEEP??
I had an endoscopic gallbladder surgery, that was a walk in the park. Tbh I’ve had headaches worse than that lol.
I’ve quite frequently skipped a night because of random bouts of insomnia, but the worst case was a couple years ago where I just couldn’t sleep for two nights in a row. So, about 48 hours awake total. Do not recommend. Definitely not after learning (and experiencing) how vital sleep is. Catch your Z’s when you can, folks. You really do need it.
a little over 60 hours, when ME3 came out I played it from midnight (or whenever a VPN gave me access) until I had to go to work, then got home and played it until I had to go to work again when I got home from work after that I just passed out until the next morning. I have no idea why I got that obsessive, it doesn’t happen to me anymore. Which is actually less fun, it never really affected my life in a major way except this one time.
