Great job so far!! Those first couple of weeks are the biggest challenge, so you're halfway there!
I am almost 3 years smoke-free now; like you, I tried to quit for years before that. Sounds silly, but I read a book by Allan Carr - The Easy Way to Quit Smoking. I also worked hard to change the 'habits' I had: walk around the block after a meal instead of reaching for a smoke; drinking my morning coffee in a different location; things like that. It was hard, no lies, but so worth it - I even ran my first half marathon a few months ago, something I could never have done as a smoker!
One day, one minute at a time if that's what it takes. You can do this!! We're all so proud of you!!!!
