why do i never blackout?

i’ve gotten prettyyyy hammered and i’ve never blacked out.

ex: last night i went out & my goal was to blackout. i probably had 10-12 shots (within 2.5hrs), it took me til at least shot #7 to loosen up. i ate a bowl of pasta right before we left and that’s all i had for the day. my friend however was up there by shot 3/4 & she had a full meal. i didn’t get sick, i didnt get hungover, i didnt blackout, i remember everything except some tiny details.

extra info; i used to be an extreme lightweight. im talking 2 shots and im pretty up there, but ever since i had my son i can take shots on shots and barely feel anything. i am bigger/slow metabolism, and have insulin resistance that has gotten worse. so im not sure if that factors in.
