I've asked myself the same question a few times since I started vaping, especially those times that I find myself grabbing my vape stick more and more.
I was smoking for 6 years, but I was never 'too' addicted to the nicotine. I would get rushes with every cigarette (I wouldn't usually smoke more than about 4 or 5 a day) but that also meant I felt the effects so much more.... I got the dizziness, the sweet sicky feeling, I could feel my blood pumping, and worst of all a sluggish that wouldn't usually go away for at least 5 minutes after the stinky.
So when I started to vape I naturally thought 'what have I actually achieved?' as my demon was the habit more than the addiction. Whilst that's still there, I don't feel like crap 5 times a day anymore, I'm not spending anywhere near as much money, and I'm satisfying my need without feeling like I'm bleeding from the inside.
I'm proud of myself, and you should be too. The habit is a hard one to kick, and as they say nicotine is more addictive than ......, and very few people can succeed from going cold turkey, so pat yourself on the back have yourself a vape, and just remember, you're saving your own life.
