I have gone without food for a day, including hard physical work. I'm not doubting that it's survivable and that was not the point of the post either.

"It's miserable yes"

That was the point, this is what turns me into someone who is not as pleasant to be with. Hangry is a very apt description.

I have tried it all, drinking water, coffee, tea, Mindfulness, go for a walk, stuffing meals with fiber to last longer. My mood will still be low and irritable until I eat something once hunger strikes.

The most fun is when you have gone without food for long enough that the shakes come and you need to eat something to be able to prepare food. Fun times indeed 😁

Right now, I'm playing the mind game of insomnia. When I can't sleep my mind gets the idea that I'm starving (which I'm definitely not), adding another reason it's impossible to go to sleep whether I give in or not 😞

You ever read House of Stairs by William Sleator?
