Thanks for your replies. Thanks for the link NQC, very helpful.
I have 8-10 cigarettes a day. Always in the garden (the children don't know i smoke). I am always washing my hands, cleaning my teeth etc to get rid of the smell.
I wish I didn't smoke, I gave up for a very long time, but stress got the better of me and I started again. Don't feel up to trying to give up at the moment but hope to soon.
