G'day Swimfan
Yes I promise it gets easier as the days go by. I found the first month quite difficult, especially when my lungs cleared out around weeks 3 & 4. It got much easier after that but even after 5 years as a non-smoker I'd still say I shouldn't be too smug about it. A really stressful situation could no doubt still make me want a cigarette so I think ex-smokers always need to be on their guard.
The benefits of not smoking are endless, so what you're doing will be well worthwhile in the long run. Good luck & best wishes. You can do it!
