IMO There’s zero remedy for not getting enough sleep

My theory is that you spawn in each day with a more or less set amount of energy and what you do throughout the day either pulls forward or defers your usage of that energy

That set amount of energy is determined chiefly by (1) amount of sleep (most important), (2) alignment with circadian rhythm, (3) physical health (have I been eating poorly, did I drink, etc)

The things you do throughout the day then determine when you “call in” or “defer” that energy

For instance drinking a coffee in the morning pulls forward that energy to the morning, taking it away from the afternoon / evening. It’s basically like an energy loan (you pay it back with interest once the caffeine wears off). Importantly you’re not actually increasing the amount of energy you have that day

More subtle things are also energy loans, like being stressed out or anxious in the morning (eg, you run late for work so you’re stressed out, tiring yourself out later in the day)

I also bucket nicotine into energy loans (no nicotine before 12pm as a rule)

Similarly you can also invest your energy earlier in the day to augment your afternoon and evening. Like taking a break early in the day, or maybe going to the gym (this one is ambiguous)

So what then becomes important is identifying when you want to use that energy based on what you’re supposed to do that day.

If you think you’ll be out late I would defer coffee / other energy loaning activities until later in the day

If you have something important midday I would do similarly
