Depends where you sleep?
How about getting out of the house. Go for a walk. Go swimming. Go watch a movie. Distract yourself from those.
You sleep as much as you need. As to the video games, that's another matter.
Get out a bit more. You might find someone to get into bed with! Even Mrs Thatcher managed 4 hours a night. She was addicted to running the country unfortunately. I wish it had been video games in her case.
Keep some target to achieve by which your career will be successful.. Strive for it. I am sure you will not find time to play video games.
