From toast to cigarettes

A few months ago, I had a consultation with my oldest friend, Jo, who also happens to be an NHS Dietician. She gave me some dietary advice, some of which I have managed to follow. And the results have been great. My IBS is greatly reduced. Amongst other things, I have stopped eating toast and dried pasta. I thought I would really miss toast, but you really do get used to not having something after a while. Perhaps I can apply the same thought strategy to cigarettes...
