Sudden constant hunger

Yesterday I ate lunch normallly at a restraunt before evening shift. Soon at work i got severe stomach pain. I took protein drink and paracetamol just in case. Did not help much. Later I ate little bit of salad because everything else sounded too much. Well that helped.

At home i felt still bot of the same squeezing paing in my stomach, so I ate small portion of rice and chicken, ice cream and some dried fruit. These helped again.

Now it's 4 am and I've woken up for the third time to hunger. I had another protein drink earlier and now some more rice and meat.

Last time I felt hunger pain this intense that i need to almost gp home was when I had ED

Do you think this will pass? Why is this happening?
