How long till I can smoke, drink, have sex after testicular varicocele surgery?

Ok I'm in my early twenties and I smoke weed and cigarettes occasionally mostly while hanging out with my friends. I have no problems smoking or drinking now while I have the varicocele but tomorrow I'm getting the surgery where they put a camera thing through your belly button. Well I was planning to get drunk on New Years since I always do and I don't know if it would effect the surgery healing. Would I be able to start smoking again the next day after this surgery?(cigarettes,weed)? Also when can I start having sex/ masterbating again after this surgery? Thank you for the answers
