question: Hi.i am male 25 years old.i am a student.i am always absent minded,could not able to concentrate and i cant remember and recall things  and while writing a question paper i have to concentrate for 3 hours and after 3 hours there is dizzy vision and i cant see properly.for this i feel that it is because of excessive masturbation because i masturbate 3 to 4 times in a day and this i am doing from last 6 to 7 years.and i read on internet that excessive masturbation results in dizzy vision and absent mindness and its because while ejuclation we loses cetain harmones or elements from brain and that causes absent mindness and dizzy vision.please advice me how can i recover from absent mindeness and dizzy vision.Thank you.
