My first week being a non smoker

Started coughing blood on 21/02/2019 gave up smoking straight away, as of today 01/03/2019 8 days no smoking, brought a nicorette quickmist but I believe will power is working better, I only use the spray as a mark of respect after paying $30 for it, I am doing more as in going out, for exsample I went to Fairfield yeserday(live in Granville) but I had to walk 300-400mts to the station, when I got to the station their was no heavy breathig like a week earlier
