I don't have a problem with file bloating, but I did have random freezes of the game as soon as Skyrim updated. It was getting ridiculus. I fixed the problem by removing the Unofficial Syrim Patch and going here and downloading a different patch Unofficial Skyrim Patch: http://www.darkcreations.org/forums/files/category/21-hosted-projects/ Ironically, after installing this downloaded patch via nmm and placing it as the first .esp file in the load order, the problem was solved. It ironically improved my load times, not sure why, and cleared two quests that had been completed but would not show as such? Anyway, I have had no problem with this patch thus far. Not sure if it would help in your case but thought I would throw it out there.
