Most likely you're bored and it's head hungry not physical hunger.

Could be indigestion. Indigestion takes on a different feeling after surgery. You can get incredible "hunger pains". Call your doctor and tell them. They may start you on medication and you'll feel better.

@Chelly, I like the boredom piece, but I must say it has really felt good to get some much needed rest from a month of hard mental work. @pegsbored, I will ask about that,but veer towards not needing medication. Good to know that it could be indigestion, I'll research this and find out what others are doing naturally for this. Thanks for the advice!
