I found switching to low strength brands like silk cut before I gave up helped me. Although in the end, it was a sore throat and a very bad cold that brought it to a close on the streets of Barcelona. Funny how you can vividly remember these things.
I realised I was smoking , and it was actually hurting my throat , and I decided there and then to give up. I bought some chewing gum, wrigley's and haven't touched a cigarette since, 8 years ago.
I would add I had been under a relentless campaign from my youngest daughter to give up. She now smokes , and I'm returning the favour.
Good luck for all those trying to give up, it's not as hard as it sometimes seems.
