I am suddenly reminded of that scene in the second Harry Potter book when Ron is burping up slugs and Hagrid tells him "better out than in."
When I had my gall bladder problems, all of my gas got trapped inside and I could neither burp nor poot and boy, when I got to hurting bad, how I wished I could have let something out. Now that I'm back to something approaching normal, I burp and poot almost as much as a regular person ought to and I really find being able to fart joyous. LOL! I went for five years pretty much without being able to, getting to do it now feels like such a relief.
