'ER' star Noah Wyle remembered the long, grueling hours of shooting for the show, which came to a head one night when he was shooting and doing a play in Hollywood and had come down with mononucleosis. "I had a fever of 104 degrees, and I was hallucinating," Wyle said. "I didn't think I was going to make it. I turned to Dr. Joe Sachs, our medical tech.... he looked around the set and said, 'I guess I could take one of these IVs and give it to you.' There were IVs all over the set. He squeezes a bag of saline into me. When we were shooting, I'd put it in my pocket.... I was twenty-two or twenty-three and working eighteen hours a day. Going home seemed like it wasn't on the table."
