Hi. I am speaking on behalf of my boyfriend.
He is 24 years old, tall, athletic, normal health. He works mon-fri 6 hours day, does phyiscal activity 2-3 a week for 3 hour periods. But his problem is on weekends all he does is sleep, the entire weekend. He does drink every night, sometimes in heavy amounts, which plays a part in his lack of sleep. He is worried that something is wrong with him but will not see a doctor. My main concern is why does he sleep all weekend and still feel tired during the week days?
