I'm a little late to the party, but I started my quit in October after a slightly scary trip to the dentist. The hygienist, and the dentist both agreed that there was some tissue change in my lip, but decided it was not drastic enough to do a biopsy just yet. I will be going back in a about a months time, but that Friday October 5th around 10 p.m. was the last dip I put in my mouth, weather what they found in my mouth is serious or not, I will not stop my quit. At any rate I have referred to this site at least once or twice a week since I started my quit, but was reluctant to join. I just wanted to say thank you to all the people who have posted so many encouraging words of wisdom and support you have be speaking right to me without even knowing it! Good luck to everyone on this bitch of a journey... quit on!
