Tummy Rumblin's

I'm getting the hang of the whole "sip, sip, sip" thing, but I'm having a challenge figuring our if I'm hungry or not.  Does this typically happen to fellow WLSer's or is it only me.  I always felt like this when I was pregnant where I would eat and then feel hunger pangs about 10 minutes later.  Well... I'm not preggers so what is going on?

I feel like Hamlet, but for me it's "to eat or not to eat?" Do I raid the refrigerator for a SF Jello or pudding.  Do I opt for a protein shake to curb the sensations I'm feeling?  Or do I sip yet another mouthful of water, hoping the sensations will subside?  What to do, what to do?  Is it in my mind or is it my body telling me I need something???
