There's an interesting post at the Victorianist weblog, "The Little Professor," on sickening poetry. The author rightly notes that you have to go to the eighteenth century to find the really sickening poetry, and quotes Swift's "The Lady's Dressing Room." It is certainly Swift at his most merciless; of all idealisms he disliked, I think he disliked the idealism of the romantic affections most. Some of his other works are in a similar vein, but more moralistic about it. You can find the link to the poem through the above link; it is not for the faint of heart.
