I used this forum to quit the first time in may of 2009 after having smoked for 15 years, and had been quit for two years. For some stupid reason I allowed myself to have one here and there about a year ago, until I realized I was buying packs, one per week then every other day. This time I hope to quit for good being a bit wiser and realizing that I am not able to just have one here and there and going cold turkey like I did the first time. I am on day four now, yesterday was rough, headache, feeling out of it, irritable and somewhat on edge. Today feeling much better. Trying to just get through it one day at a time.
Good luck to everyone else quitting as well!
