Hi doctor, I am not able to sleep properly since past week. I had a total of 20 hours of sleep in the whole week. I wake up in the middle of night and its extremely difficult to get back to sleep again. Even during the day, I don't get sleep and my mind is not at all active. It lost focus, concentration. I am taking too much time to think. I am having only avg of 2-3 hours of sleep a day. I changed my sleep cycle various times during last month. I had a lot of stress as well due to various interviews. Can you suggest me treatment.
