Hello and Welcome!!!
I too was a secret smoker - only those close to me knew. It was exhausting!!! Once I quit for a period of time, then re-started. I hid my smoking from everyone! It was such a drag! Hiding to smoke, covering the smell, having to wait til I got home, then be angry that I couldn't sneak away for my fix because my kids needed me or something. Ugh! It was awful!
I had the guilt & shame too, so I understand about that.
The absolute best thing about quitting is all the freedom we get back in life! It is so refreshing and relieving, so very worth any of those tough moments when I wanted to cave.
During previous quit attempts when I failed, I found myself getting into those arguments with myself - I want/I don't want, etc. When I became successful is when I wouldn't allow myself to have those inner arguments. I'm not smoking anymore. Period. End of discussion. I can get angry, cry, punch a pillow, tell the dog to screw off, whatever, but I was not going to smoke.
When I felt the urge creeping up, I would distract myself - come here and play a game or start a new thread, shower, pet the dog, eat some peanuts.
You can do it! :)
