its not good to make multiple threads on the same topic just because there was not an answer as soon as you would have liked.
but no its not a good idea, the number one cause of death by opiates is because they were combined with benzos.
if you already took several benzos and 80mgs oxy you should feel good already, go relax and enjoy your high and you can take the tramadol tomorrow. also, one of the reasons your previous thread may have gone unanswered is because is it very hard for anyone to give advice on how much of a drug to take due to everyones tolerance is different and everyone responds to each drug different from another person. also if someone was like "yeah thats fine! have fun!" and then the user took the drug and something awful happened i dont think the advice-giver would be feelin to great about him/herself
and if you're thinking "fuck it, i dont care, ill just take the tramadol" you probably are only thinking that BECAUSE you took the benzos, so do yourself a favor and just dont add any more drugs to your cocktail
