Having ocd for the better part of my life, i've been looking for new ways to help it. I have found strenous exerise to help the symptoms dramatically. This requires pushing yourself to your physical limits. I mean hard breathing...
Also, if you are on an ssri, if you take your meds only once a day, taking a small amount at night may help you sleep better, as serotonin helps to regulate sleep, and by thee end of the day most meds have, for the most part, warn off. Consult your doctor before changing your meds.
