I told t pretty early on in therapy. However, I did start doing it again shortly after I told him I used to. When I finally mustered up the courage to tell him I started doing it again, he did not terminate. He was vey calm about it.. We talked about what triggered it, how it makes me feel better etc.. He does say that he wishes i could find a better way to cope. Most t's that I have heard about here on the boards only worry when it is serious enough that it needs to be checked out by doctors or if you are doing it a lot.
