Is water supposed to feel 'heavy' in the pouch?

I am so glad I found this thread!  Drinking water after my RNY is the weirdest feeling I have ever experienced.  It almost feels like Braxton-Hicks contractions when I was pregnant.  I can feel it going down and sitting in my pouch.  I don't experience this with any other liquid (except, as some of you said, Crystal Light Lemonade).  I thought it was because I drank it cold, so I started drinking it at room temperature, with no change.  Glad to hear this is "normal." 

Thanks again!!
