The honest answer: most people need both. They serve different times of day and different states.
Start with the bigger problem
If your mornings feel chaotic, your focus is scattered, or you're stuck in a coffee-crash cycle: start with MHODE ON.
If you can't switch off at night, racing thoughts at midnight, or waking unrecovered: start with MHODE OFF.
If both: start with the Bundle.
Two ends of the same system
Recovery is performance. ON without OFF leads to burnout. OFF without ON leads to drift.
The two together are the position — day and night, switching deliberately.
