I took benzos and oxy

So I took 1mg of Xanax at 7pm felt nothing at 8 and took another one. Smoked a couple bowls and took a dab and was only high from the weed. So then I took my xtampza 27mg (oxy 30mg) at like 10 but I did the thing where you put it in vegetable oil and heat it over a candle. I am now currently nodding off for a good few seconds every now and then tall think imma black out?
