I'm sorry you're having a rough time right now. Caffeine and carbonated beverages definitely talk back to me too lol. It's hard, but you just have to slowly cut it out of your diet, if you haven't already. I am pretty certain it's trapped gas. Try and keep yourself distracted as best as you can. I always play computer games that call for my full undivided attention. Addictinggames.com is awesome for that. Good luck and I hope you feel better!
