The quick Lesson on this sites that in the negative imperative the subject pronoun (tu, vous, nous) is dropped.
In Schaum's Outlines text, I see the following negative imperatives: Ne te reveille pas, Ne nous reveillons pas, and Ne vous reveille pas.
One of the exercise questions in chapter 5 of same text asks for the negative imperative of "Promenez-vous dans le parc" The answer is Ne vous promenez pas dans le parc.
