Dr Litch is just plain foolish. He believes that since e-coli is something that many people in 3rd world countries are forced to live with, it isn't that dangerous and insisted that even severe cases of it can't do any long term damage! He didn't take my complaints seriously at all and treated me like I had no right to any knowledge of my own. He was incredibly arrogant and condescending. Needless to say, I only went to him once.
