Traveling tomorrow, what if I can't sleep?

This is insomnia caused by excitement and compulsion. I suggest you relax, don't force yourself to sleep too deliberately, think about the consequences of not sleeping in time, and deliberately break the biological clock, which will only make it harder for you to fall asleep. You can read books and listen to some light music. If you don't go to bed so early, you won't easily affect your trip tomorrow. Don't be upset because of sleep ~ I hope you have a good trip tomorrow!
