I had this problem several times when tried to get better spawn place. I was killing myself some times then when got better spawn place I started to eat and drink. My status was not changing, but after relog I started to vomit immediately.
I think there is a bug with spawning. For example, I spawned in Kamyszowo (sorry, writing on phone and don't remember English version) and was running straight to Elektro. When I was near I was dying of starvation and dehydration. Didn't manage to reach water pump near school. I'm gonna open new ticket with this if I don't find one exists.
