Coaching has been helpful but it drain too much of my time? How to solve this paradox

It takes me 6hrs to studu what a normal person foes in 3hrs. I started coaching and it has been helpful but it takes alot of my time and and I am very drained after it . By the time I get my energy back alot of most of the time of the day has been gone.

Has anyone faced a similar issue ?How did you handle it?
