Ending a sentence with "however"?

Question

today I got into a discussion with a colleague of mine about if it's correct to end a sentence with "however". Here's the case:"I've attached the following document. I don't think it'll be useful, however".Although I think the sentence could be better written, I don't think it's wrong to use "however" ending it. My colleague's opinion is that it would be better to use "though" on it.So, I have 2 questions: 1) Is it ok to use "however" in the end of a sentence, with the same meaning of "though" ? 2) Which one is better in this case, "however" or "though" ? Thank you!

Hi!

Speaking technically, the word however is post-positive, which means it should come second in your sentence.

"I've attached the following document. I don't, however, think it will be useful."

This would be the most correct way to write this sentence, as ending with either however or though is not quite correct.

Best,
