My two cents about using meds...

To my point of view, some reasons might make it necessary to use meds when fighting Ocd.

One of them is, ocd has biological effects on the brain and this causes some imbalances related seratonin.

Second one is, ocd is chronic and most might get diognasis and access appropriate treatment too late after onset of the disorder, thus some compulsions and obsessive thinking patterns may unfortunately be automatic before you aware of them. So you might have to work on them very hard.

Third one is, learning cognitive theraphy tools and understanding symptoms fully -that is a necessity- takes a while that contribute negatively maintain your suffering.

I believe, Ocd can be beaten without meds, only if you should master CBT and apply it consistently on your waking life and have courage to work on aggressively your each symptom by using exposure and response prevention.

I also believe that, one can terminate using drugs when have gained some grounds from ocd and created totally immersive environment that give chances to do exposure continually...
