Stress definitely affects ibs! I have been stressing majorly today, lots of scary things to do today, and my bowels have been going mad! I have constantly felt like I need the loo but can't really go but have to keep trying anyway!, which is really bad while I am here at work, and I have pain and grizzly growely feelings, gas...you name it I got it! And I know it is because I am stressing! Help! need to relax! deep breaths...ouch!
