The mods are going to tell you not to use swim here. so for future reference I wouldn't use that term. And there has been a lot of new to oxy threads popping up on here lately. If this is your first time using opioids of any kind, 15mg should have in most cases for people who are opiate naïve had you feeling good. I know that was the first opioid I ever tried, 15mg of oxy except it was up the nose and it was a roxy not a Percocet. I felt incredible. hey maybe oxy isn't your kind of drug. I would stop now, and never look back if I was you. I wish I never tried oxy but I did and cant change that, and that 15mg of roxy my first time turned into over 8 years of being extremely addicted to every kind of opioid I could get just to keep from being in withdrawl and chase that awesome opioid high which I didn't always get once I became truly addicted. Anyways its your life and if you don't care about all that and are going to continue to try oxy no matter what advice you are given, I would try a little more like 5mgs at a time until you find what your looking for and feel it. It may never happen though, some people just don't react well with oxy and some do. maybe like I said its not for you. BE CAREFUL and don't go overboard popping 5mg more over and over, if you don't feel it by 25-30mg I would consider stopping. also its best to learn how to do a cold water extraction with percocets, because all of the APAP in them is really bad for you in large amounts. you might want to look into that on the search engine or google. Its not very hard to do. But seriously, if this is your first time be super careful and be smart, its not hard to OD on oxy if you have no tolerance.
