Today, while looting the office building in Krasnostav I glitched through the wall and landed in an un-enterable and therefore un-escapeable room. Annoyed, I ate a rotten kiwi, minimized the game and booted up Minecraft, waiting for my character to die.
At the time I was "Healing," "Stuffed" (appears to be a permanent status now), "Energized," "Hydrated," and "Sick." I came back an hour later to find myself dying of thirst, but my character was still Energized and Healing, and no longer sick.

I went to class (1 hour 40 minutes) and came back. My character was in precisely the same state: "Stuffed," "Healing," "Thirsty (red)," and Energized. An hour of homework and two hours of Minecraft later, again, still alive with those same status effects. Eventually I was able to glitch back through the wall, hydrate myself and resume normal play.
This...seems like a bug.

TL;DR: Energized, Stuffed and Healing appear to be permanent (given that you don't throw up) buffs, and this is not likely working as intended.
