How to say: "What's the longest you have gone without sleep?" or the pattern for "the longest one can go without something"?


I've decided to start practicing speaking by answering random (sometimes
ridiculous) questions from the internet. My first step is to try and translate
them from English to Japanese as best I can, since it helps thinking of the
answer.

So I came across this question and cannot find a way to translate it.

> **What's the longest you have gone without sleep?**

I thought of 睡眠なし and 寝ずに and 最長 and 時間がかかる, but I cant know for sure if these
make sense and I cannot put it all together. I would really appreciate if
anyone could tell me the best way(s) to do it.




> I thought of 睡眠なし and 寝ずに and 最長 and 時間がかかる

There is one word redundant. I mean you need to choose either「睡眠なし」 or 「寝ずに」.

「最長」 is appropriate to "the longest~" though,「時間がかかる」is awkward. It literally
means "It takes time". But this time, you need an interrogative pronoun
:「何」since grammatical form is what-question : "What's the longest~"

Also you should replace 「がかかる」since it is rather asking "how much is the
longest time you have been in the sleepless state" than "How much is the
longest time you have used for not taking sleep".

For example, 「過ごす」 or 「いられる」, etc. should work well with
either「睡眠なし」or「寝ずに」but not both.
