I work in a night shift. And I tend to feel sleepy all the time. At work i keep dozing and my head keeps dropping. When I talk to someone I feel active. When I go home in the morning, I feel sleepy again, and I get going with other chores to keep me up. I sleep at 12 PM in the noon and wake up at 5 PM since my office begins at 6 PM in the evening. I usually follow the trend of having dinner at 10 PM in the evening and breakfast at 08 AM in the morning. I am not sure if my eating habits are affecting my health, or If I am in the heart disease lane or if I need to change my habits. Over the weekend I follow the regular schedule what normal people do, but its just during the week I follow the above mentioned pattern. Please advise If I should change something. I am 22 Years old, 5 ft 12 in and 89 KG in weight.
