Specific Insomnia!Dean fic

[nympha_fluminis]

So, I've been looking for this fic for awhile. I'm pretty sure it's Standford Era, and one day Dean just kinda shows up Sam's door and at some point admits that's he's been having trouble sleeping for awhile and hasn't actually slept at all in a couple days. Sam takes him to a doctor and Dean the doctor starts asking stuff like, "how long do sleep at night?" "do you have trouble falling asleep, staying asleep?" etc and Dean replies with something along the lines of getting any sleep at all for the past 5 days.

And that's all I remember. If you guys could help me find it, that would be wonderful! :D Thanks!
