Is this "normal?"

You have to think of it like this: It is thought that we have a crazy immune system. Our IS is in overdrive, constantly fighting with our body - in our case, attacking the colon or whatever is in the colon. In essense, it makes us tired - some of us all the time. Over exerting one self can put even further strain on the body. When I over exert, I tend to feel sickly weak and yes it can even affect my stomach. But if I drink a lot of water or fluids then it doesn't seem to be as bad. What meds is he on? Does he do stuff after he eats?
