Hello all, thank you for your patience as this is my first post to SPN StoryFinders, or LiveJournal at all for that matter.I'm looking for a fic where Dean finds Sam intoxicated and Sam has no recollection of who Dean is. Although Dean is adamant about the fact that they are brothers, Sam has an entire tragic history which has led him to become a drunk adult. Dean will not give up and kidnaps Sam to try to figure out what is happening. At some point, Sam runs away, Dean tackles him, and Sam twists his ankle. I think that Dean also drugs him at some point so he can casually go to get food with him. 

Thank you all for any help you can provide!
