Looking for a post about Moonlight 3rd

[yamaha]

Hi 

Now that my exam is over I would like to go back and finish learning the Moonlight sonata (which was originally in my exam programme but I gave up on it because I thought the Pathetique would be easier  )

It is of course the 3rd movement that I need to work on.  I remember some time ago reading a post about this movement and Bernhard replied with specific ways to practice it 

Can anyone point me in the right direction of this post?  I have searched and searched but I cant find it 

Thanks
