When waking up the players should be a little thirsty, maybe like -4 points from before the sleep?

Awesome idea, added it dc1ba65

When you check the commit, the players hunger gets reduced too but only the half of the thirst :)
Will add a config

Ohh that's really good, was at work so I only had time to write a comment.

Could you please do the same with hunger? It would then be consistent and logical.
