Shaky and internal restless

 I'm three years post op bypass. So is my wife. From time to time, we both get a very shaky feeling and very restless internally. We yearn for something to eat, but don't know what. The only thing that makes the feeling go away is time, but there is a very strong desire for something. Anybody have any ideas?  It's not dumping and I have checked my blood sugar during an episode, it was fine. 

Second issue is my stomach has gotten very sensitive lately, can't eat much.  I'm down to 142 pounds. I'm a 6ft male.  Skinny as a rail and still loosing. Ideas would be appreciated.
