Hi, I really appreciate your reply to this thread. Which is weird, because I quit smoking (again, 30 days ago) and had cravings yesterday and today. And then I get this message from you. (I have not been active on this forum since 2009) So I find it really wonderful (and a bit strange) that you should send me this message right now, out of the blue, at the perfectly appropriate time, when I was seriously doubting myself. I think it's a sign. Thank you so very much fo your words of encouragement. I have been struggling and am worried about my lungs.
