I'd start by not sextuple-posting, it just sextuples the ugliness ;-)

Anyway, I think parsec is *far* too big a hammer for the nail you're trying to hit.

import Char( isAlpha )
import List( groupBy )

equating f x y = f x == f y  -- in Data.Eq, iff you have GHC 6.7

isLetter x = isAlpha x || x == '_' || x == '@'

myWords = filter (isLetter . head) . groupBy (equating isLetter)
