As the title suggests, I slept for 3 hours on the day I went home on the 7th, and then came back by plane, and lay down at about 2 o'clock in the evening, and my sleep schedule for these two days was seriously insufficient...... Yesterday was also more than 2 o'clock to sleep, today the whole day was groggy, now sit in front of the computer for 10 minutes and can't help but want to lie down, today I take a leave of absence I will sleep early...... Tomorrow at least 2 more to make up, if the state is good, 3 more (to be continued......)
