Yes, once realized, the financial savings can be a huge motivator to staying quit. For me, I decided to take up vaping for health reasons as I was convinced that if I kept smoking as much as I was, my days remaining on this Earth were quickly diminishing. As you can see below I was a heavy smoker, and once I put the actual figures on paper as to how much I actually spent a day, a month, a year on smoking the realization made me sick to my stomach! Armed with the will to quit (health reasons) and the motivation to quit (financial reasons) it was easy for me to say goodbye to the stinkies. And after 1 year and 6 months after my last cigarette I can safely say that I have never felt better! Life is good again because I can breath, smell and taste things I had forgotten about a long time ago!
But the important thing to remember is to go at your own pace and don't force yourself. Making the switch to vaping should be a good experience, not a forced resentful one. With each day that passes without an urge for a cigarette should be celebrated! Milestones are important on your journey as you make the switch, so reward yourself with something with the extra money you have saved, or do something you enjoy that you really couldn't while being a smoker. It's your life and your journey so enjoy the moment while you have it!
