I spent several years using caffeine as a way to squeeze more hours out of my day. Typical week I’d spend four nights staying up until 2am getting focused time to solve problems and code. The sleep deprivation was starting to impact my physical health so I cut the caffeine out a year ago, and now it’s difficult for me to pull more than one late night a week. The sleep benefits have been great, and in that time period I moved into a chief engineer role with a lot of travel and customer interactions and less straight technical work. Overall I have higher quality output despite fewer hours of focus time, might be a different story if I was still needing to produce the same quantity of code. I find coding tends to have a dopamine effect and keeps my brain engaged well into the night, but other activities rely on more rest to accomplish the attention to detail required.
