bs indeed, any vodka that's produced industrially should be filtered well enough for it to be just clear booze, and have hardly anything in it other then water and alcohol
it's not like vodka has much "flavor", hell, the word means "water"

anybody who get's hungover from vodka , simply drank to much of it to begin with
or simply can't process alcohol... either way, it's would be in the bottom of the list of hangover prone drinks if there ever was such a list
