I use Claude Code on production codebases enough that I hit the max limits. "Vibe coding" does not describe my work. A deep understanding of software engineering and computer systems is required to make the calls that keep a complex codebase healthy and keep my company’s

30 minutes nap in the middle of the day: absolutely destroyed. Needs 3 more hours or zombie for the rest of the day. Waking up 30 minutes into the sleep at night: fully recharged. Back to sleep? What sleep? Body is ready to start the day.
