Hello Friend, Good that you are seeking a help here. Excess sleep could be due to tiredness or stress because of your exam preparation. Get on to some brisk excersise routine, change in your daily routines and dietary changes. Don't try any medication without consulting as it can harm and give side effects. Call me directly or online through Practo app for further detailed evaluation and suitable recommendation that you can follow practically to overcome this problem. Be positive. You will be alright soon.

I think you need more energy by way of clarity and planning, to get translated into action....instead of medicines. It would be better to consult a psychologist for more clarity.

Consult psychiatrist near by  u who can prescribe the medicine for you.try to read in the morning   go bed has  early has possible
