In 2002, at age twenty-eight, David MacLean came to, standing dazed and confused on a train station platform in India. He was alone, in a foreign land with his memory wiped clean. No money. No passport. No identity. Taken to a mental hospital by the police, MacLean then started to hallucinate so severely he had to be tied down.

Soon he could remember song lyrics and scenes from television shows, but not his family, his friends, or the woman he loved. All of these symptoms, it turned out, were the result of the commonly prescribed malarial medication he was taking. Upon his return to the States, he struggled to piece together the fragments of his former life in a harrowing, absurd, and unforgettable journey back to himself.

David joined Sean today on the show to talk about his book,  the controversial use of malaria medication in Guantanemo Bay, understanding his sense of self and the fear of it all happening again.
