Since I quit binge-eating sugary stuff, my body became capable of feeling true hunger. Not in my stomach, as that kind of feeling in my body is probably fucked up forever, but in my head.

When I feel hungry, it’s probably too late. This is exactly what I feel:
- dizziness
- FOV slightly decreases
- tunnel vision, things in peripheral vision become blurry and obscure. I “see” them, but my brain doesn’t process them quite as good
- colors become less saturated
- it’s very difficult to combine and analyse multiple concepts to derive a conclusion, basically the thing I do at work that wins me bread
- thought process becomes “single-threaded”. I can follow just one thought at a time and cannot go deeper than 3-4 levels, my brain just drops it by making the whole thought feel like some kind of slimy clay that cannot be comprehended, let alone expressed with words
- difficult to express thoughts with language, I have hard time talking, especially explaining
- want to sleep, but can’t, as brain is frantically trying to stay awake

It’s probably the mechanism developed evolutionary. That single thread remains active at all costs to allow me to find food, and brain doesn’t let me sleep, as it thinks if I fall asleep I’ll die. It’s amusing to see my brain actively killing thoughts that are not “important”, I feel like a real-time OS or an Erlang application. Perhaps thinking is really a very costly process in terms of how much energy it takes.

When I finally eat something, especially if it’s a proper meal, I feel a very pleasant sensation, probably it’s my brain telling me “thank you”, releasing dopamine to actively reinforce that “finding food is a very very good thing and it’s very important”. FOV pops back into place, peripheral vision becomes clean and sharp, thoughts awaken, eager to occupy all the treads that became available.
