The difference is astounding to me. 10 days in - before, it was difficult to go jogging sometimes, because it would hurt my chest, I'd breathe and pant so damn hard. Believe it or not I smoked while hiking the past 3 summers - I worked on trails, hiking 1000 miles a summer. While smoking. I was in such good shape from the hiking that I didn't notice an effect, but after each winter of not being very active, it would be tough to get started each summer. Or tough to start jogging, period.
Now - 10 days in - each day I am jogging somewhere between 2-5 miles, sometimes without slowing down for a walk break once. I go trail running when I can. The other night was symbolic for me. Think it was on day 7 or 8 or something. I went up a mountain, 10.5 mile round trip, trail running the lower 3 miles each way (the flatter sections, rolling terrain). When it got steep I kept a fast pace. When I got to the summit, I basked in the breeze and the view, and thought - never once did my chest hurt from breathing. I caught my breathe quickly, busted out my MVP2 and Wakonda, and vaped, and asked the mountain to bless me and help me to never smoke again. I declared to the view and my home--the Adirondack Park--"I am not a smoker. I am a vaper."
Sometimes, while jogging with doggy, I slow down to a walk break and vape while I walk. Then I pick up jogging again with no effect on my ability to do so comfortably or sustainably.
Sometimes, I still cough up phlegm, but most of that has passed now. The cravings for cigs have been completely and totally replaced by the craving to vape. I have no interest in stopping vaping. I've always loved to smoke - the act of smoking always pulled me back when I'd stop for a few months. And each time I quit, for at least 2 weeks I'd be miserable, angry and grumpy, irritable as hell. Only on day and 2 were I mildly irritable from quitting by vaping. With vaping, I can continue to "smoke," with none of the things that actually concerned or bothered me about smoking.
If some things about vaping are unhealthy--fine by me. It's certainly healthier. I can be active as hell as if I didn't do anything at all. I don't have to worry about what the guests think I smell like (I'm an innkeeper, kind of important). I don't have to worry about Chrissy thinking I smell awful as she hates cig smoke - and in fact, she loves the smell of vape, and we vape together sometimes! Almost everything else I do in life is healthy. I'm a very active, very fit, vegetarian. So you could say I'm VV! Not variable voltage--Vegeterian Vaper

It's good to be concerned about what we put in our bodies and I think that's why most of us are here. It's good to pay attention to real research about vaping as it continues. But unless it's ever shown to be as harmful or more harmful than cigs--I will VAPE ON!
