Way to go! Congrats on your quit and good luck on your surgery!
I have surgery in 5 days, however I have taken the Chantix medicine, I"m on the 2nd week as of yesterday. Unbelievably as a Chain smoker, I no longer smoke, and this would be the way to go, I have swabbed, and no nicotine in the system after 7 days.
nicotine is water soluble, so 3 to 5 days
I'm told 3 days. Are you being tested for nicotine?
