Lung test

[nsd_user663_42084]

Hi all, i quit 2 weeks ago after 3 weeks of being on champix, today i went to see the nurse at the clinic and she said next week shes goin to bring a machine with her to test the age of my lungs to see what the extent of the damage has been done to my lungs. Has anyone else had this test?

Started off with a CO2 reading of 59 that was 5 weeks ago and today its down to 2. So chuffed i get a certificate in 2 more weeks
