alright ive got about a tablespood of tequilla left and I need to get drunk tonight.

Heres what I got

3 Coronas
8 Mikes Hard Lemonade
Vanilla Extract
bout 2 shots of some 40 proof shit.

I don't wanna drink it all and get caught though. Can I like drink half the bottles and then fill the rest up with water and hope it looks normal? My parents will never drink it, its just left over from when other people were here.
