Hi, I am 24 years old girl and student also. I am preparing for civil exams. My exams will come soon. and I do hard work to clear my exams. But sometimes I am suffering from problem which I actually do not know what is this. I sleep around 12 pm and wake up at 8 am. After waking up, I start study for my exams but now a days I feel pain behind my eyes and feel sleepy and I don't want to study. I also Take green tea, coffee, strong tea n power nap to boost my energy. But nothing can't work. I want to study for my better future but this problem cause obstacles to my study.
