20 % peprmint liquer + choclate whole milk ?

i only drink like 3 times a year max so i like to try random things

i really like mint chocalate so i thought this could be nice alcoholic drink alternative

i was thinking 500 ml of the liquer and 500 ml of the milk

my weight is 72 kg and im 24 so i think if i would drink it in a span of 3 hours i would get properly drunk but not shitfaced plus im planing to smoke weed after i finish drinking

you guys think it could be a good drink ?
