Fred I am not knocking my daughter, I am concerned for her. You say e-cigs don't kill but you don't know that for a fact. As I have posted before, they are unregulated, so who knows what rubbish is being put in them by unscrupulous people? She is in such a bad place since she ceased smoking cigarettes, bad tempered, rude, aggressive, ill mannered, sullen, now hates a job that she has loved for 10 years, fallen out with people at work she has worked quite happily with previously. She's totally unapproachable. I just want my lovely daughter back. This has been going on for over 3 months and when I do try and talk to her she bursts into tears and keeps repeating 'it's so hard'. Of course I'm pleased she's given up smoking and I praise her for that but she now seems to be in a deep depression and won't go to the doctor. My own experience of giving up smoking was good, hers seems to be a nightmare with no end in sight. I don't know whether e-cigs are playing any part in this, how would anybody know.
