I've been vaping and smoking for several years now. I started at 18mg of nicotine over 4 years ago and have worked my way down to 3mg. Now I have become serious about quitting smoking but when I vape my 3mg juice, I still want a smoke shortly after. Should I go back up to 6mg and see if that helps? I seem to remember that I would cough with higher nicotine levels. Not sure what to do at this point, any help and suggestions would be helpful!
