- Software Engineer - 8 hours - 3am - 11am - 8 hours feels about optimal - Normally don't drink caffeine at all. - I avoid caffeine until I need it. (during the last week or so of a sprint). During that time I'm probably averaging 3-4 hours of sleep a night, and drinking 3-4 teas and 1-2 redbulls per day, all day/night long.
