How is it going so far?
I have not considered cold turkey on my OCD because it is germ & cleaning related. Going cold turkey would mean I have to set up complicated rules about when I can wash my hands, when it's ok to clean truly dirty things, and such. It is too complicated for me to just stop, because it would pose a serious safety issue for my family. I have considered going cold turkey on a few of the compulsions which are truly not a safety issue though (like cleaning grocery carts).
I hope it's going well for you though!
