Fic search!!!

[lady-psiho.livejournal.com]

Hello, i'm looking for an old harry/draco fic that i seem to have misplaced. I remember that it was a creature fic, harry was blind, because of some potion sent to him by owl, he traveled the world to find his familiar, a snake
-draco stayed with dudley, they had a sort of inheritance so harry had a collar made for draco so that the death eaters could not find him
-at one point harry helps dudley lose weight and he starts brewing firewiskey , that's all i remember. Hope you can help me :)
