Fuller reached C2 on 7 May. He is allergic to mushrooms and had eaten mushrooms at ABC. He felt very ill and injected himself with adrenaline. He felt better the following day and accompanied Roeske on his summit push. When he was way up to C2 he started getting a tingling in his face again. He collapsed. He injected himself with Dex again and descended to C1, where he forced himself to stay awake. On the next day he descended to ABC and a Sherpa came up to bring him oxygen. Apparently it was a toxic shock from the mushrooms.
