The beauty of PVs is that you can take a hit when you want then tuck it away.
I'm in the process of weaning myself off analogs and so far I've been able to cut my consumption into at least half without a concerted effort.
Like others, after using PVs, I've found the smell of analogs undesirable to say the least.
As for general tips on quitting, I've found that you need to find alternative reasons to help you carry you
through. For me its my love of food and cooking. The fewer cigarettes I smoke, the better I can taste my food. Sometimes its the little things that matter.
