I am getting tired soon just when reached to office. Feeling like dizzy while walking in the office and concentrating the things..i know lot of things about the topic but during meeting or discussion not able share my thoughts..or recall the points properly..even after meeting I thought that I need to reply in such a way on the problems/discussions.when wake up in the morning after getting sleep of 7 hours feels like I need to go for another sleep of few hours with body pain. What to do ?I need to get rid of this problem asap.
