Dear Sir / Madam, I am having problem of feeling sleepiness throughout the day. U wake up at around 6 am and my office starts at 8am. After the reached after about 2 hours, I feel drowsy. Then all through the day it keeps coming and goings. I keep yawning several times the day. In the evening I feel better, but after I reach home at around 7pm and freshen up and have evening tea, I feel sleepy again. And most of the time I sleep for around 1 hour. Then I wake up have my dinner and sleep again at around 12.30 am. Kindly advise if I have any problem and what should I do for it. Regards, Modhumon Chowdhury
