Sandy edits  
My issues with this edit: Removing the Mary Larimer material; creating the "Other Criticism" second and removing most the Thirteenth Stepping material; the Arthur H. Cain material is an opinion piece from a source that doesn't have a reputation for fact checking.  The other changes the wording I don't have any problems with. 

Sandy has a point about the Shute reference , but there's not point to have a sentence like "Total abstinence as the only form of recovery from alcoholism has been questioned." This give you absolutely no real information. The change from vs. to "or" also seems okay .
