Far far better off.
How long since you smoked, and did you smoke a lot?
Within a couple months of stopping cigs, I stopped my little "hack/cough" that I really didn't realize I did so often...I stopped coughing up "stuff"...I stopped getting "winded" just from climbing some stairs... All good.
And that was about 3 years ago.
I've reduced my nicotine (though I still use more than you) - but just because it's easy to do. I make my liquid, so every month or two, I lower it a tiny bit, and don't even notice. I don't CARE that I'm using nic...I just figured, "why not?".
