Here is the list of the fictions that answered my challenge:

Not-So-Magical Medicine, by Comic Nerd (who has my many thanks as she is the first).

You can find it here: (FFnet) /s/5392565/1/Not_So_Magical_Medicine

Or on her profile: (FFnet) /u/1789713/Comic_Nerd

I'm sorry for the messy links, but you know how it goes on this website... Hard to put a working link ! ;)

Thanks again !
