The natural supplement, NAC, helps lessen the severity of my OCD. I take 3,000 mg on the days I feel I need it more. If I were you, I would try taking that much every day and see if it helps. It was recommended to me by my psychiatrist. Fish oil also helps the mind, but I don't know how much it helps OCD. I would also start getting vigorous daily exercise if I were you. At least 30 minutes a day of higher intensity exercise. That can be as effective as an SSRI (anti-depressant), according to some studies. Of course, follow through with seeing a psychiatrist and therapist, too. Good luck!
