I feel sleepiness all time, at the time of study. I try for many types of check up. After observing the test reports the doctors says, 'you are OK, there is no problem with you. I can't understand about your problem.'.
To get rid of this problem is very emergency for me because if i cannot stop this problem then i have to stop my study. It is impossible for me to continue my study with this problem. Please help!
Thanks in advance!
