As everyone has stated, moderation is the key. However, this is easier said than done for some people. Everyone starts out as a chipper, using occasionally. However, if you do wind up addicted to opiates, you're likely to not even notice it's happening at the time, or delude yourself into thinking you're still in control. A pill just once a month can lead to every Saturday, which becomes the weekends, then it starts creeping into your work week, then every day, until you wake up one day without any pills, and you're in withdrawal. I'm not saying this will happen to you, but as it's been said before, no one plans on becoming an addict.

I speak from personal experience, as I've been addicted to pills and now heroin for quite a few years now. I started off with oxy, just like yourself and many other people. If someone would told me at that time that I would become a junkie later in life, I probably would have laughed in their face and said, "That will never happen to me." But it did happen to me, and I've lost a great deal because of my addiction.

So my advice to you is to be very careful with opiates, as its addiction is insidious. If you do plan to keep using, I'd suggest to use a calendar to mark off the days you do use, and see if that number of days gets larger over time. Also, using no more than two days in a row, with at least 1-2 weeks spaced in between use, will help prevent you from being physically addicted, because opiate withdrawal is horrible (and horrible is an understatement).

Addiction has no boundaries. But maybe you're the type of person that does have the self-discipline to not spiral out of control. I have to tell you though, I've met plenty of intelligent and driven people that also got caught up in opiate addiction, and I'm fairly certain almost all of us would take it all back if we could.

Just my two cents. Be safe, friend.
