When I realised I had symptoms related to being a smoker, I found a local stop smoking clinic. I used the patches and nicotine inhalator. I am so glad I have quit! The temptation is still there because I had smoked for a long time. It wasn’t easy but I followed the advice I got from my advisor and used Nicotine Replacement Therapy. That way there was no able to fail and I didn’t suffer cravings.
I haven’t had a cigarette since, and I would say good luck to anyone else thinking of giving up.
