I quit 8 months ago, but sometimes it feels like just yesterday! I couldnt have done it without Alan Carr and nicotine gum. His way is pretty against NRT, but this is what has worked for me so far. I keep telling myelf that I am going to quit the gum, but so far I havent.
Honestly, after reading his book, quitting was not that hard. I have hard moments, especially lately which is odd with all that is going on with COVID and breathing issues.
The most important thing, for me anyway, is that I wanted to quit more than anything in the world. If you are determined to do it, you will!
My breathing impoved a lot quicker than I thought it would. Good luck! I love being a non smoker!
