Alcohol and 0.5mg Ativan

I take 0.5mg Ativan as needed for anxiety, and I took a small sip of Rum tonight. This may be a silly question, but will I be okay? It was about an hour maybe two apart? I don’t want to fall asleep and not wake up. I know that you aren’t supposed to mix them at all, but I just wanted to taste the rum my friend got for her birthday.
