I used to, I think these days I'm about as close to cured as ever happens. OCD is one of those things where you probably already know what you need to do to get out of it, it's just the thing that you can't do. For me, I had to just accept that if I didn't check the locks that I might just come home and find that all my stuff was gone. And that the house might burn down if I forgot to turn off the stove or completely switch off the lights. And over time it did get a bit better. But, I think in most cases, that's going to be asking far too much if it's been allowed to hit a point of complete and utter crisis.
In cases of crisis, it's usually a combination of therapy and medication. But, at the end of the day, the only thing that actually works is generally the thing that folks with OCD can't generally do, especially if they don't get help early on, it's just let the anxiety and panic build up longer each time and try not to engage in the rituals or just greet the intrusive thoughts as if they're clouds. And, I'll say again, that that is not even remotely easy, but over time it should help a lot. Therapy, medication and meditation will probably help at least somewhat.
