After running some tests to check for apnea and asking questions, his diagnosis was “you work too much, can you work less?”. Lol, maybe if I cut food out of my budget.

So fucked up, work is basically hurting your health :-(

Here in France that discussion would go: "you work too much, putting you on health vacation for a week, we'll increase if you're still feeling exhausted after that week". And the state would pay you during that week.
