WTF? Without a tolerance this would kill you, im 100% sure, im a very big guy, and I have some tolerance to opiates, I have done oxycodone several times, opium smoked and in tea, tramadol, oxycodone+benzos+alcohol etc...
And 50MG of oxycodone plus the alcohol would kill me, im sure, thats an extremely heavy dose for an opiate naive person, just by itself it would probably be unpleaseant and intense and cause vomiting although it probably wouldnt kill you by itself.... my usual dose is 20-30mgs of oxycodone, when I did oxy+benzos+alcohol I used 15mgs oxycodone, 10mg diazepam, 0.25mg alprazolam and a glass of wine, and I had some tolerance to these substances... that dosage and amount of alcohol will kill you if you are opiate naive, if you have tolerance it depends of how much tolerance, but im well over 200 pounds and very experienced with opiates and that mix would kill me.
