I think if I reckon I went about
27 hours without sleep. Not bragging because it's shitty when you get double vision and migraines and sluggish reflexes and tiredness followed up by sleep deprivation

4 days when I was a teenager. Lots of caffeine and starcraft. I started hallucinating by day 4 and basically passed out from sleep deprivation. Ever since then I have a really hard time staying awake more than 18 hours or so.
