However, to control it I suggest you watch less porn if applicable in your case.  Yoga, meditation helpful in such a case. I suggest you practice early morning light exercise. You should focus on study and make short and long term goals for study.  You can take help of psychiatrist or sexologist for detailed evaluation. Hope I have answered your query. Let me know if I can assist you further. Take care Chat Doctor.  </s>
