Congrats. Today is smoke free day 25 for me.
From what I've read your lung function drastically starts to improve at around the 3 month mark.
I'm still winded walking up a flight of stairs, but I'm waiting for the months to go by and see how things improve.
Just remember, no matter how long you've quit for, one puff and it'll be like you never quit. It's that easy to start again.
