Good for you Purple!
It is easy to cheat and lose progress if trying to progressively wean yourself from the nicotine habit.
With the help of Chantrix I quit successfully after two attempts. First time I permitted myself to gradually decrease as the drug instructions permitted, then I cheated and resumed smoking.
Next time I went "cold turkey", i.e. quit totally with no progressive decrease in nicotine dosage. That was five years ago and not a single cigarette since.
Wishing you total success. Maintaining willpower is difficult if you allow yourself to sneak a cigarette or vape now and then but you already know that.
