I went to the doctor to see about giving up smoking, becaue I want to and also because I want to get pregnant. So I go and discuss this, I am a heavy smoker and have tried and failed with patches &c before but to no avail - in fact the only time I HAVE given up is when I was pregnant with my son. My doctor prescribes Champix - apparently very effective for the hard core addict. So I buy this, £7 or whatever the prescription is, and read leaflet at home. DO NOT TAKE Champix if you are pregnant or planning to become pregnant. Great.
