It is a weird way of saying that your sickness is leaving...
I had blurry vision and discoloration forever. I kept eating, drinking, running to digest and eat and eat and drink and drink. I took the charcoal tablets because I had enough of black and white vision and now I'm sick...
Would any of the devs finally explain how the hell the health/energy system works?

Fire Axe is OK as it should be in real life.
It is the other melee weapons that suck
The baseball bat is useless (by the way can we get rid of the baseball bat... I don't think they play baseball in former Soviet Union)
You cannot even tell if you are actually hitting the zombie, it should at least keep them at distance, but instead is like you are doing just nothing to them and they keep hitting you. The melee animations are just terrible

I get the thirst message, then I drink a whole can and i'm still thirsty... fix it please
