I quit at the beginning of this year but sadly restarted. I hope I can one day kick the habit.
What made you start again. Seems quite an achievement to go so far then relapse.
Other people smoking around me at work. This triggered me to smoke one again.
It takes a long time to quit smoking. It's almost impossible to quit in one or few days If you have smoked for years, If you do so you would feel really bad because your organism is already "addicted" to smoking and needs It. Best to do is stop gradually taking less and less cigarettes per day till you'll finally take none. This can take several months or even over a year.
