BBC commented that one ounce of pipe tobacco seemed like a lot. I guess it is all a matter of perspective. For me, one ounce a week is a significant reduction. Typically, I have been smoking on average 4 ounces of pipe tobacco a week. There have been times earlier when I have been stressed when I would even smoke 6 ounces a week, but that was several years ago.
One ounce a week is definetly a decline, and I notice it quite a bit, but that I think is the point and purpose (I hope). I am trying to regress successfully to being a non pipe smoking person by "unlearning" my previous patterns of consumption. I am now picking and choosing times I really would like to smoke my pipe far more carefully, and I hope as I progress to find I have fewer and fewer "really want to smoke my pipe" times. That is my current working theory. I hope it is not just a pipe dream... pun intended.
