Am on day 2 of quitting. Had just recently given up for 7 weeks while had badly ulcerated mouth but although knew it was crazy to smoke while mouth in bad way, felt really low without the nicotine fix! Mouth finally got better after steroids and I went back on cigs 2 weeks ago but started getting pain in upper back and lower back so think that was my body's way of saying enough is enough after nearly 40 years! Thought it would be good and nice to chat to other people trying to now live with major change without nicotine!!! My thoughts are with everyone else trying and big fair play to all of you who are on the way already!
