My husband started vaping with me a year and a half ago, but he's given up and gone back to full time smoking I still smoke a few a day too but it's far better than the 3pad habit I had! After 38 years of smoking, I never thought I'd even cut down!
I'm sorry to hear that your husband started smoking again. It's great to hear that you have managed to hold the urge at bay (for the most part at least). 3 pad is serious business and I'm sure your health improvements speak wonders.
Hopefully, I can convince my wife to stop altogether. For now I'll just keep her batteries charged and her carto's full while hoping for the best.
