Hit my two month mark tonight. I have had my ups and downs but vaping is here to stay for me. Worse part has been the addys for my SE. I kill them quickly. Because of that I have had about six packs of cigs in the two months, spent way to much trying to keep the SE going and have been frustrated with the whole process. That said my health is great! My doctor is so pleased and has recommended e smoking to other patients. I got my fisrt 510 yesterday and REALLY love it. The button is great, it makes me much more conscious of how many puffs I am taking and the clouds of vapor with increased taste satisfies me. I think the constant hard pulling on the SE was killing them and making me nuts. Even with a high nic level I had to have the SE in my hand at all times and was continually dripping and fidgeting with them. This 510 is much more relaxed and satisfying. It doesn't look so much like a cig but feels more like smoking. $240.64 spent on kits, parts, pieces and cigs. $273.48 saved on not buying the smoldering death dealing Benson and Hedges every day. I think that is a fair trade. It should get easier and cheaper form now on.
