I haven't experienced that, but it could be a beta endorphin effect. Illness, pain etc can cause a beta endorphin spike, and then as you withdraw you feel hungrier (there are receptors in your digestive system). I used to get ravenous the day after drinking alcohol because of the beta endorphin spike and withdrawal.

I wouldn't worry about it. You could try eating a little extra fat and see if that helps. Once I understood what caused my bottomless pit hunger (which I still get to a lesser degree once in a while, although I don't drink alcohol any more) I would eat a little more fat and go for a walk and that helped.
