I have had it start up and the Doctor's at my Veterans hospital sent me to a Nutritionist to alter my diet, and it worked fantastically.
The Nutritionist had me to eliminate Glutens from my diet because they cause the IBS to flare up. The rest of my diet was to stay the same, because I avoid sugars and sugary drinks and foods and greasy fried foods. She suggested that I add one supplement daily to aid my Bowls in digestion and it works great. It is taking two 500 mg Turmeric and Curcumin tablets daily. They are both in the same tablet, and I take them once a day. You can buy them over the counter at any store, I get mine at Walmart for lack of any other stores in my rural area. I buy the Spring Valley brand. Oh, you can take them anytime of the day you want, I chose to take mine at night just as I go to bed and they have worked greatly for me. No flares ups in the half year I have done this but check your diet to make sure you have the best results too.
Good luck this helped me greatly.
