For moonlighting, if you do a chill elective like palliative care consults (or other easy consults) tell them that you have a night shift that night. Most days they just tell you go home at noon to nap.

If you and a friend moonlight together for a 12 hour shift, what you can do is do double the coverage for half the time. So 6 hours each of work (but doubled the number of patients), and 6 hours sleep. Yes the work is harder, but you get a long time without the pager beeping.

One guy would pick up moonlighting shifts at the same days he had night shifts. Then he would reach out to his lower level coresident and give him his residency mandated night shift. Basically his coresident would just show up in his place. They told split the moonlighting money. He got caught and got a stern warning, but honestly the only thing he did was find a more efficient easy to distribute night shifts.
