A weird change

Last time (not last month, TOM doesn't call that regularly) I had a weird experience at the beginning of it. On one of those days I went through a period of a few hours where I experienced extreme hunger that just would not be satisfied. The only other time that has ever happened to me was during my two pregnancies. I put it down as a one off and ate every half an hour or so until it was satisfied.

Well now TOM is here again and the exact same thing happened last night. All of a sudden I felt hungry. We are talking ravenous, belly aching, could gnaw my own arm off hunger. I had already eaten a decent days food. There was no reason why I should be hungry. So I drank a glass of water (I already drink plenty but just in case thought it was worth a try). 20 minutes later there was no change in the hunger and I was starting to feel sick and faint. So I started looking at what I could eat that would a) satisfy my hunger and b) not sabotage my week. I should have concentrated on 'a' because by the time I had eventually satisfied the hunger I had eaten almost another meals worth of food. I was eating then waiting to give it chance to register. My body wanted/needed food. I probably would have been better off if I had just had a 'meal' in the first place but I was hoping there would be a chance of easing it with a little snack.

Has anyone else experienced this? It was really strange and if it's going to be happening every time TOM pays me a visit then I would like to be able to plan for it but that is not easy because of the lack of regularity.
