I tried to quit smoking for over 20 years using nicotine cessation products.
Gum- hurt my teeth
Lozenges- turned to paste in mouth
Patches- Slid off in the summer
Nvr tried the clinical ways because they were expensive.

I started using e-cigs, but they had a set nicotine lvl. I went and bought a tank system where I can custom tailor my own e-juice.

You pick a flavor and then they ask about the nicotine percentage. The highest I can buy was 16%. Every few weeks I lowered the %.

When I hit 0%, the e-juice was gross, so I quit it all together. All the flavor is in the nicotine.

After 25 years, it's been a year since I smoked.

This worked for me and I hope it works for you.
