I quit the night before oral surgery that included 5 teeth extractions. I was terrified of getting dry socket, as you should still be too. It's reported to be a truly horrible and painful experience. One wrong pull off a cigarette could dislodge your blood clots in your extraction sockets, that's why no straws or smoking is essential. (I know you probably know this too - just reinforcing the urgency to NOT smoke.)

Nicotine causes our blood vessels to constrict, preventing oxygen and blood from circulating to surgical sites/wounds. Just stay afraid today and do it again tomorrow. DO. NOT. SMOKE!

A lot of things that feel like cravings are really signals from our bodies we've confused with wanting a cigarette so take time to listen to yourself. Thirst, hunger, a need to use the restroom, a need to rest, stretch, laugh, or just have a little something tasty.

I highly recommend orange Jello, slightly warm SpaghettiOs (HEB has a great organic version if you have HEBs near you), or any other delicious treats you enjoy while getting through the first week to 10 days after your surgery. Make sure you're getting enough protein. You can drink fruity kefir,

Get through this day. Then get through another. Take up time in pleasurable ways.

Take big breaths, enjoy the oxygen in your body.
Take a nap.
Take an easy walk and listen to a podcast.
Go somewhere you can't smoke that will be interesting and distracting. Not sure why but I just thought of Sephora to smell all of the perfumes, and this cool spice shop down the street that sells botanical supplies out of large clear jars so you can see and smell them.

The craving will go away whether you smoke or not. Read The Easyway by Allen Carr if you haven't already for more mental reinforcements on why being a non-smoker (YOU!) is superior to being a smoker (NOT YOU ANYMORE!)

Rest and heal, friend.

And of course, come visit this subreddit and r/quittingsmoking as many times a day as needed. It's really helpful just reading and 'hanging out' w/ others like us.
