I think it's good to remind ourselves that this process might take awhile. When you consider that I've been PMOing daily for ~14 years (nearly half of my life!), I think it's unrealistic to see dramatic changes very quickly. Particularly since I haven't been as good (so far) with stopping the MO, or O altogether for that matter.
I've seen some good improvements so far, even if subtle, which I've mentioned before in this blog. Just have to keep going, and see how it goes from here.
