> Every night I tell me agents I'll be going to bed and to not ask questions and keep going.

Most harnesses now support something like this:

  /goal "Work on the current plan until 11 AM in my time zone, provide a summary of all the overnight work then."

Other than that, look after your own wellbeing! Nothing wrong with letting agents work overnight, just don't overextend yourself and don't spend all of your free time on it.
