need a little bit of help

Calling all brewers. At work we sell Gold Peak Lemonade+Tea. One day i got bored and decided to throw some corn seeds and uncooked corn chips in a bottle of it to see what would happen, expecting nothing to come out of it. well, after being stored in a slightly airtight bottle at room temperature for about a week, it gained an alcoholic smell and the bottle was bloated. seeing this “alcohol”, our first thought was to try tiny sips of it. me and three other friends all swallowed small amounts. how fucked are we? what are some outcomes to be expected? also try to spare me the lecturing to an extent, i feel like shit about it. i currently have a headache and a stomachache, but that could be from me not sleeping at all last night. sorry this is stupid lmao.
