Hi there... I'm new to the forum and am in pre-surgery stage (submitted already to insurance, just waiting to hear back and get scheduled). Your topic interested me because I had to quit smoking in order to have this surgery. I quit by switching to a vape pen and Non-nicotine vape juice. It really helped me. A couple weeks later I gave up the vape pen too. I had been a smoker for over 20 years. I knew when I bought the vape pen I would only be using it temporarily, so the cost didn't bother me, since I had been buying cigarettes for so long. I just racked it up to the cost of quitting, and for me it was more sensible than nicotine patches or gum.
I wish you the very best in this endeavor.
Take care of you...
