Sam/Dean with MPD or DID?

 Hey y'all

I was wondering if there were any stories with Sam or Dean having MPD (Multiple Personality Disorder) or DID (Dissociative Identity Disorder).  They're the same thing, but the name changed  a few years ago.  I'd prefer if Sam has it, but I won't be pick if Dean does.

I'll take Sam/Dean, Sam/Castiel, Sam/Gabriel, or Dean/Sam/Castiel.

Thanks guys!!
