Hi!This is in response to Fry's first question. It is very common to have your IBS related to stress, it is referred to as a "Brain-Gut dysfunction". Have you tried hypnotherapy for your stress? http://www.helpforibs.com/ has a great section on Hypnosis for IBS. I would definitely look into it. I know it's not everyone's cup of tea, but it is definitely something to look into. It has had a lot of great success!
