Nightshift CNA here,
I eat dinner with the wife at anywhere between 6-7:30 just depends on the evening. And then I eat lunch typically around 12:30. But sometimes as late as 2. Work a locked behavioral unit, so lunch depends on the moon phase lol.
I drink my coffee starting at 9pm so it fits in the window. Coffee is more effective several hours after waking, and you really shouldn’t drink much for 4-5 hrs before bed. I’m sleeping WAY better having started fasting.
I do pretty well waiting until 6 the next day to eat. I sleep, wake up and have some plain tea or just water. Sometimes a bit of hunger but by dinner time I could almost take it or leave it.
