Razorback,
Yours is a great success story! I am sure you feel much better, and the weight, though it may concern you, is not as dangerous as the smoking was. I, too give away set-ups to people who would like to try vaping. More, and more people are interested, as our stories of giving up the cigs, is spreading far and wide!
Join the CASAA and carry your story to the FDA, or Big Tobacco will win and all we will have will be cigalikes. (YECH!) It was so easy for me to start vaping, it was everything, smoking used to be: a way to relax, smoke indoors, and not smell.
The protanks make it enjoyable to vape. You got the right idea. Keep it up and vape on, and on and on!
