The headline doesn't follow her story correctly as she hasn't beaten the problem: she is still on a very restricted diet if her words are true - pity they don't spell the word correctly too! 
There is NO common sense surrounding phobias, whether it be of spiders, buttons, vomiting, blood …… there is logic but this logic flies out the window when the fear takes over.  Dr Raj Prausad [sp] began the treatment protocol that she is following ……. he offered me a place at the Maudsley many years ago [? 1990s] but I was unable to travel there due to the phobia.  
I have tried to re-claim my Life but once the fear begins, any logic is gone and I am a shivering wreck in the corner of a room until the emergency medication kicks in.  With the BB I can cope better most days but I know how quickly the fear can paralyis me.
