Say it isn't so

I was blog-surfing last night.  I came across a blog by a young gal who spent part of last year as an au pair in Vienna.  It was funny, interesting, a little sad (the au pair job didn't work out and she's now back home).  I was enjoying my read and all was going along fine until I came across a line, something about .... access to Diet Coke being extremely limited.  Um.  Why haven't I considered this?  Please. Somebody.  Tell me this isn't so.
