@sea: hey that's a great point. That's one of the complaints I've heard from my friends, is that they don't know when to stop puffing! You don't really realize how important the "ritual" of smoking is until you stop. "Marking time", I'll have to tell my friends about that.
I think the ritual aspect of it for me is super important. vaping is different than smoking, but still allows me to focus on my breathing and of course have nicotine in my system.
