Hey,
I was supposedly diagnosed with IBS from my gastro years ago. However, from reading many posts, I don't think I suffer major symptoms like IBS sufferers.
Have you ever tried "iberogast"? It is a german or chinese herb that many find relief with. I have a study about it, but I do not have a scanner to upload it. The study was done by Naturopathic dr's in clinical trials, with random samples, blind, the whole deal.
You can find the product on Amazon.com. Look at the reviews and research more about it. Research the product and ingredients.
If you do try it or know someone share your or their story with others. I am not trying to sell the product to you, but do your research.
I will tell you I have never tried it because my symptoms are more from the gut and silent reflux rather than IBS or severe heartburn
