I am a UPSC preparing student . Due to the disturbance in my home during day time I practiced studying in the Night Time . I used to start my study at 8.30 or 9.00 in the night and go to bed at 5 or 6 in the morning. Now it has become my routine , I am not able to adopt to the normal life. I want a solution for it . I want to sleep as early as 9 and get up early at 4.30 or 5 . I have tried a lot practically in order to change myself but everything ended in failure . Tablets always gives as side effects , So is there any practical treatment or any way in accordance to change myself to a normal Life.
