While never a heavy smoker I absolutely loved vaping: it was the first thing my hand reached for in the morning and the last it let go falling asleep. I went into panics when I couldn't remember where I had left my vape.
I've now managed to further reduce my smoking to only very few cigarettes per day. This might well still be more harmful than vaping all day long, but at least I got rid of my sixth finger (as a friend used to call it) and I can forget about smoking or vaping for many hours a day.
