If I quit smoking, how long will it be before the nicotine gets out of my system? How long will the physical withdrawal last

It takes three days for nicotine to leave your system. However, nicotine metabolizes into cotinine and can be detected in the blood several months after cessation, but cotinine does not cause withdrawal. Withdrawal symptoms from nicotine usually last for about two weeks and can include any number of the following: fatigue, insomnia, coughing, dizziness, chest tightness, indigestion, hunger, flatulence, constipation, phlegm, hoarseness, leg pains, stiffness, diarrhea, sinus congestion, tingling in fingers and toes, bleeding gums, sore tongue and increased thirst.

Be good to yourself during this vulnerable period: Avoid gas-producing foods, drink eight to 10 glasses of water a day, gargle, do deep breathing every day, rest, reduce sodium intake, take warm baths and exercise.
