Sleep disorder: You don't list an age but adults function best with 7-8 hours of sleep/day, teens often need 8-10. If he falls asleep playing games he has a sleep issue, not a tumor. Vomiting as he awakens from sleep would be a more likely scene for a tumor. He needs to see his PCP and work out a realistic way to enjoy the pleasures of his life, while addressing the need that his body has for sleep.
