hello! i tried alcool+benzo several times at doses ~30-50mg, sometimes with other things like antidepressants. basically, you fall quickly in a coma for 1-3 days, then you wake up in an altered state of consciousness with a delirium for 1 week. it can be worrying because when you wake up you can think weird things like "will my brain be like this forever".
benzos = low dose for toxicity but really high lethal doses, unless you have respiratory problems (amplified by alcohol).
ultimately no consequences. not worth it
