D.L.
I have had IBS for 15 years and didn't want to admit how much anxiety played into it until about 7 years ago. I found out that when I took a sedative I didn't have IBS problems!! Lightbulb moment for me. So since then I always carry Lomotil (anti-diarrheal-prescription-cheaper and better than immodium) and valium (very small dose-doesn't even make me sleepy). As long as I take these far enough in advance I do pretty well. If I'm not driving, I can take more if needed :) BUT Something that I discovered recently is--gluten makes me anxious and gives me IBS problems!!!! I went on a gluten-free diet for about 4 months and my IBS completely cleared up!!! NO anxiety either. I fell off the wagon about a month ago (vacations and company and sheer craziness around here) and have gone right back to my IBS woes. I am hopping back on the gluten-free train now and looking forward to feeling better. Also, fyi I did not test positive for celiac or food allergies--just can't tolerate it I guess.
Hope you find some relief. Yoga and regular exercise helps a lot as well as oatmeal in the mornings (not instant).
