I'm 58yo and had smoked for over 40 years.... I thoroughly enjoyed smoking and only started vaping to try and reduce the amount of cigarettes I was going through. The cost of cigarettes and associated medical repercussions were my motivation, so I thought that if I could just replace a few analogs a day with vaping, I may save a few $$$ and breathe a bit easier.
Well it hasn't actually worked out as planned coz after a few days of vaping the anaolgs started tasting awful, and after a week, I just couldn't stand the taste of them!
It's now 32 days since I had a 'nic-stick' and I can't see myself ever wanting tobacco again. The odd thing is, I honestly didn't intend to give up smoking, I just stopped wanting to.... I'm happily puffing away on my Ego-FP as I write this.... I don't smell like an ashtray, I can breathe easily, taste my food again, and am saving around $12 to $15 a day... win, win, win

. I'm laughing all the way to the bank instead of coughing all the way to the doctor.
My advice to the uninitiated would be, don't start vaping specifically to give up smoking, but to simply reduce the number of cigarettes you smoke; that way there won't be the stress associated with " I have to give up". After a while, you will probably find you prefer vaping and the ciggys will just fade out of your life... if not, then at least your use of them will be reduced, and that's gotta be a plus.
