I used to smoke, I gave up first when I was 14, second time at 24, and that was over 20 years ago.
Last year I started working with a friend of mine who had taken up vaping and decided to make it into a job/hobby, and that's when I started vaping, first of all just to get a feel for the equipment we were selling, and so I could give honest opinions on the flavours. I have to be honest, I struggled with anything over 6mg, but didn't mind vaping 6mg as I am aware of the effect of dopamine release that nicotine has on the brain (vaping makes you feel good - fact), however I didn't
need the nicotine, it was just extra. Thus I started mixing my own eliquids in zero nic, and as I have a sweet tooth, I started mixing sweet flavours.
I'm still vaping now, almost predominantly zero nic, my two current favourites are Vanilla Custard and a blackcurrant menthol blend. The bonus in all this is that I now vape when I fancy something sweet (rather than when feeling the need for a cig, which passed years ago), and as such I hardly ever snack, so I've lost a stone and a half in the past 6 months.
For me, vaping has definitely had a positive effect on my health, my weight loss has diminished my high blood pressure so I no longer have to take the pills my doctor prescribed.
Obviously everybody's experience will differ, but for me it's all good
