2. Chronic sleepiness or tiredness is a common symptom.
Looking at a screen all day will make the symptom worse. You’ll start to halfway close your eyes or put your head on the desk to go to sleep. Someone will have to constantly wake you up. The reason you’re tired is that you didn’t get enough sleep the night before. If you did get any sleep, you probably woke up several times and couldn’t go back to sleep.
At work, it is important to listen to what is being said because the company has to run smoothly. For instance, in most jobs they have meetings. At the meeting, your eyes may close. You may be one of the people that have to lead the meeting.
On the other hand, you may want to contribute to the well-being of the company, but your opinion doesn’t get said because you were sleeping the entire time.
