I am 20 years old, male and I have a problem. I take 7-8 hours of sleep regularly but still I feel like sleep in my eyes always. I don't feel energetic. So I try for a siesta but in vain. I can't sleep at noon or afternoon, when I lay down to bed different thoughts cover my mind and after sometimes I wake up from bed forcefully. I have vertigo and head pain. So how can this be healed? Please help doctor. I'm in serious trouble.
