This is not a self-control issue. The short rest classes are built around taking short rests more often than long rests. The current rest system means that every third rest needs to be a long rest. That isn't how the classes and rest interplay is designed to function.
When my friends/kids play D&D that is exactly how we play.
Short rests are lunch and dinner.
Long rest is sleep.
You get twice as many short rests as long rests.
Too many short rests tend to tip the scales too far for Warlocks, Monks, Fighters and Moon Druids.
