This feeling goes away, right?

The first month is the worst.  I had a case of buyer's remorse at the five day mark.  

Right now you just have to take small sips, and take them often.  It will get better when your stomach isn't so swollen.

I'm two years out and I can guzzle water as I did prior to surgery.  It gets better.  Hang in there 

I'm 5 years out and I can guzzle as much as I want.  I believe it was 1-1.5 years out when I could first guzzle.
