I "found" a bottle of Darvocet-N 100 (PROPOXY-N/APAP 100-500) I was wondering if they are any good, I looked it up and it says it’s an opiate, but I’m used to taking oxy’s or hydro’. Do they have the same effects? How do the doses compare, bc these say 100 mg each, I’m used to taking like 3 pain killers that are 5-10 mg each; So how much should I take?
