really stupid question

really stupid question, but im curious

what could happen if i were to take 20 mg of melatonin and down it with 0.10 litres of cosmopolitan vodka? would i just pass out? would i be able to force myself awake until some point? would i be able to wake up the next day at approx 8 am? lol i stopped taking melatonin, i was taking it for only a few days and those were very little doses, it didn’t do anything of course. im 166 cm and 52 kg.
