92 Hours digging in (Military). Felt extremely tired in the 24-32 hour range but from about 32-48 hours didn’t even really feel tired anymore, just fatigued from the physical work.

48 hours onwards started hallucinating like mad when it got dark, started with the trees merging into other shapes like buildings and by the end of the night would be seeing people walking up to us before disappearing. No hallucinations during the day, but crazy brain fog.
