Levitation EffectsFollow

Someone mentioned to me in-game that they have seen a file which will eliminate the "bouncy" effect of the various levitation spells but couldn't recall where they saw it.

Does anyone know? Even a hint as to where to start searching for such a file?

I suffer from severe vertigo and the bouncy effects of any form of levitation are pure misery for me and usually force me to camp within 10 mins or so. So many raid encounters require having DMF or some form of levitation to counter knock-backs or gravity flux. I hate abandoning my guild so often because I become too ill to continue.

Your help is appreciated!
