My son went to camp and I went back to analogs.

You have to remember its a process not a goal, now that being said I will share my experience. You can reduce your analog use with e-cigs but you cannot completely eliminate them and have them about. No more than a junkie or an alcoholic could keep their drugs of choice tucked safely into a closet. For exactly the same reason.

Is an occasional cigarette harmful? Who can say and the science certainly won't tell you. I'm a long term smoker who went through this transition. I have captured that experience and a process, take a look at the thread "How to switch to e-cigs for long term smokers" in the new members forum.
