Are there any cases in which the adverb "too" can be used at the end of negative sentences/statements?

If so, would you please give me a few examples?

Thank you.

Almost always you should not use "too" after a negative statement (use "either" instead). According to a thread in another place, combinations such as the following, where a negative follows an affirmative, are deemed acceptable by Swan's "Practical English Usage":

He is lazy. He doesn't study too.

However, I'm not sure I would personally particularly recommend this pattern.
