I'll share my experiences.
I smoked a little over a pack a day for 25 years: No coughing, no lung pain. Used nicotine gum once for three weeks: No coughing, no lung pain. Have been vaping now for my fourth week: No coughing, no lung pain. So, yeah, I guess it varies from person to person.
I didn't even want to quit smoking. I only got my starter kit cause I was going to be traveling, and cigarettes when traveling are a huge nuisance. I am so glad for this forum that I got a kit that works for me! Also, I think that if I had started lower than 18mg, I would have went back to analogs. Since I started vaping, the only cravings I had for analogs have been purely mental, and not nicotine related. And as soon as I start smoking one, I'm like, "Why are you doing this? It's so primitive!" And then I reach for my vaper.
