How long does it take for the smell of alcohol to go away?

I started to drink ~400ml vodka (%40) around 8pm. Now it’s 12pm. Finished drinking 3am. I had shower, brushed my teeth and chewing gum right now. How long will it take to smell to go away. Also can my room might be smelling like alcohol? I didn’t leave cap open. I stored drink in refrigerator. I ‘m ventilating the whole house. I also sprayed my room with home fragrance. I’m over 18. I have strict parents.
