Get captain beefheart out on full blast
Get all your cycling mates around and set up a workshop to fix all their bikes and your bikes in every room, that includes upstairs with shoes on.
I second Hobbes' suggestion re a N+1 order -in fact order all those components/accessories that you've had your eye on.
As each room is now full of bikes, set up a temporary bed in the living room and watch 3 dirgy dvds in a row. Order yourself a takeout- the most unhealthiest thing you want and hug your new purchases whilst you bed down after the film marathon. There may even be a cat cosying itself on your living room make shift nest. There may also be one or two drunken friends lurking somewhere after botched mechanic attempts means they can't cycle home.
I draw the line at pissing in the sink though!
