Query: Good book

As a retired Navy photojournalist I have been a fan of Tim Page's work for years, however his book Page after Page puts a whole new spin on Page the man. Yes I was aware of the drug use and abuse by many members of the military and media in Vietnam, but I was deeply disappointed to learn, from Page himself, according to his book, that he was a drug addict from the day he arrived in Vietnam until the day he left. But, then, I suppose one does what he/she feel is necessary to survive.
