Hi Barbara, just wanted to let you know that I'm in your corner. I had a really hard time quitting smoking after diagnosis and surgery also. Quit for a while but went back about 2 months after surgery. I refused to stop trying to quit and finally have a successful quit going this time. I know about depression and it was one of the factors that led me back to picking up a cigarette the last time. I take antidepressants too and they help me. One of the biggest problems with smoking was that I was beating myself up all the time, and the depression got worse for awhile. The cravings are pretty much everyday, but not all day long. When they hit I chew on a piece of sugarless gum and it helps. I also joined the quitnet forum on the internet. I pledge not to smoke on a daily basis with others and so far that has helped me not to pick one up. But no matter what, keep enjoying your life. My best to you and thanks for the post. Nancy O.
