I am really frustrated and will extremely appreciate your help!
My brother has a problem. He works from home (computer) and always does it during the night. He says that he cannot concentrate during the day, thus, has to do it at night. He goes to sleep everyday at 8:00 a.m. and wakes up at 4:00 p.m. This is normal for him.
My mother is really worried. It's been like that for years already, and it only gets worse. Before, he used to go to sleep at around 5:00 a.m., but now it's already 8:00 a.m.
He's saying he tried changing it, but he simply cannot.
What is the problem? How can it be solved?
I really need some consultation and advice, please help.
