The doctor, my allergist, and my psychologist told me that everything is in my head. I have an appointment with my gastroenterologist on the 11th of January. Hopefully, he'll help me out. Even if he doesn't, I'm still going to schedule a colonoscopy and endoscopy. And thanks for the advice. I'm going to continue to eat yogurt. I get Stonyfield organic plain yogurt with active live cultures. I also take an acidophilus probiotic supplement. Do you know if it is too much? Should I only eat the yogurt and discontinue the supplement?
