Hi, I'm looking for a few stories that I saw a while back and a general search to see if there are any existing stories that cover what I'm interested in.

1. First off is a story about Sam having asthma. I remember reading how Sam let himself have a bad asthma attack purely to torture and punish himself. If anyone knows or has written any stories similar to this, I would love to hear. [Found]

2. Secondly I've seen stories where Dean becomes blind, an OC becomes deaf and Sam becomes mute. I've also seen a few stories where Dean is mute and am interested in an AU story in which Sam is mute either from birth or some point during his childhood.

3. Third is a little odd, but I'm really interested in Sam's relationship with food. Over the entire series I've only seen Sam eat about four times and it's only ever one tiny bite, all other times we see Sam looking disgusted by Dean's eating habits and declining offers for food (mainly also is that Sam is pretty ripped, how is he getting like that when he never eats more than a nibble?). This one covers eating disorders or supernatural influences (vampire, demon blood, maybe even a vampire-demon hybrid of sorts, perhaps Sam can only drink demon blood? etc). I would just like to read something that addresses this odd phenomenon of the show. [Found]

4. Is there any stories where Sam, or Sam and Dean, are some kind of were? Not a bizarre hybrid of man and beast, but turning completely from a Human to an animal. Shapeshifter-esque.

[Edit] 5. Does anyone know of a story where Sam has to protect his Stanford friends from something Supernatural, or even just Human? Stanford days would be great. On the same note, is there anything on an AU where Sam stays evil, and someone who knew Sam back in Stanford or remembers him saving their lives on a hunt gives their point of view seeing Sam evil, as like King of Hell or something?

They're all mainly Sam centered, but I'm open to Dean's POV or even stories where say Sam's eating habits are only briefly mentioned. I'd prefer no Wincest, but I'm not 100% against it. Slash is absolutely fine, as is het.
