Wow, a whole day without sleeping? That sounds like a crazy challenge!😜Your sentence is perfectly clear! 👍 If you don’t mind I'd love to share a little casual tip with you. If you are talking to friends, you can say: ‘I'm gonna see if I can stay awake for a whole day.' It sounds super natural! (Here is my challenge! 🙋‍♂️ I tried to translate this sentence into Japanese as a beginner. Please correct my Japanese if I am wrong^^Thank you! ) 「私は一日中起きていることができるか見てみるつもりです。」
