They tell you to stop because it thins your blood which can cause lots of different issues, it also delays healing. I stopped smoking fags when I first enquiried about a BA, but I vaped instead. I stopped nicotine a week before (was advised two), but I’m still not having any nicotine. To be honest, it’s painful enough as it is without slowing down the healing process with a fag. But I suppose it depends on your will. I tried the first week and failed, not sure when your surgery is but if you can implement small changes a while before, it might be easier xx
