You didn't ask a question in your last post; you just added alcohol to the mix and informed us you were doing this shot while your mom is out of the house, so either you're a minor or an adult who, for whatever reason, is still under his mom's supervision.
Your original question has been answered; many have chimed in to assist you, yet you mentioned not a word about whether you are planning to have someone with you, or any other measures you've taken to protect yourself from harm.
No one is going to tell you that what you are doing is safe, no one is going to tell you you're for sure going to be ok, no one is impressed with the choice you're making, and you're not taking the advice given so... I'm confused... what is it you want again, and what does it have to do with HR?
