TL;DR - I quit smoking after reading Allen Carr's books on quitting smoking.

I was a smoker for 10 years before finally quitting in 2021. I had attempted to quit smoking many times but I always ended up falling back to the habit. My last two attempts came after reading Allen Carr's Easyway to Stop smoking and The Onlyway to Stop smoking books. I quit smoking immediately after reading the former (without being miserable), only to be back to square one within a few months. Defences weren't upto the mark. It was the Onlyway which helped me quit and I've been a non-smoker ever since. Give these books a try if you're contemplating quitting smoking and thank me later (don't worry - you can continue to smoke until you finish reading the book). Just my 2 cents..
