I had a septoplasty surgery 2 weeks ago, and i continued smoking a packet & a half every day, what should i do?

I went to my family doctor and told me today that i had an infection in my nose, caused by smoking, did i ruin the whole operation by continued smoking? Do i need an other operation? My nose still hurts when i touch it and right now i have a very bad taste in my mouth, it's all going down from my nose, from the hospital they did tell me to stop smoking but i smoked anyway cause i thought it wouldn't be effected much, i don't know what i was thinking
