This book was so important to me. I'd listen to the audible over and over when I felt like I was missing out. I literally lived to smoke. I never thought I'd break free. Never thought I'd get over it. It took some time, but it wasn't the unbearable, insurmountable black depression I was so scared of due to previous attempts.
It was mind over matter this time. (If you don't mind, it doesn't matter.). I did what Alan Carr said, even though I felt silly. Every morning I'd say to myself, 'yippee, I'm a non smoker.' It helped!
I can honestly say I am grateful every day not to be chained to the smokes. I have zero desire to smoke now (I used to pray so many times I would wake up and somehow the urges would be gone. Didn't happen that way). It can take time but that is so normal!! Most of us complained A LOT. That's what these boards are for.
You are right where you need to be! I'm about 10 lbs heavier still now years later, I'd like to think it's muscle but it probably isn't. That's ok!! Being a super skinny corpse is not an option. But using food as a crutch took a bit longer for me to overcome. One day I realized that particular problem had slowly faded when I was not paying attention. I say this only so you realize it may not be all peaches and cream, but it's all doable and bearable.
It's so helpful to have a community that has been there, that understands exactly where you are. You're doing just great.
