Also, if you're on call 24/7 and getting burnt out, you need an effective way of shedding this load. And it just so happens that one of the effective ways of shedding this load is a real ass-kicker move: come up with a plan to improve your ops and make it so anyone can be on call, not just you. This probably means improvements to monitoring (clear signals that don't constantly false-positive and require the expert -- aka you -- to diagnose), improvements to reliability, and improvements to ops documentation (clear docs that say when this alarm goes off, here's what you do). Sharing the knowledge that's in your head so you can stop being a hero is a next-level maneuver, and as a bonus, it gets you some peace.
