Sorry you need to have surgery--but congratulations for deciding to quit smoking for it.
Smokers don't do very well with healing after certain surgeries. I am not sure about yours, but I had a surgery 9 1/2 months ago and I quit before it because of the information I read of the percentage of smokers who did not heal well after it.
I did it cold turkey, as you are planning to do. I was a smoker for over 20 years and had tried quitting before to no avail. This time it worked wonderfully.
My advice would be to stay away from other smokers as much as you can--at work, etc. If you live with someone who smokes, it's not that easy. But, don't keep them company when they go out for a smoke. Stay away from watching people smoke as much as possible.
Try munching on carrot sticks, or another veggie you like to curb your need to have that hand/mouth reflex going. Maybe gum, sugar free, would work for you. Reading in your spare time is a good thing--if you really enjoy the book it takes your mind off everything.
I wish you much success in your surgery and your stopping smoking!!!! If I can be of support, or just an ear--I am more than happy to be here for you.
Keep us posted on your journey of quitting and how you are doing before/after surgery.
Good luck to you!
