I would seriously NOT use subs in your case (I hate them, period, but that is another story)..., your habit is not even close to a terrible habit.., the biggest danger you have is of it getting there..., for years (like 12), I used oxy for pain and occasionally recreationally, everyone i knew that had a habit always said that i was truly the one person they thought could do opiates/ opioids recreationally and truly walk away...i let that get to my head and i'm going on two years of approx. 210-300 mgs of oxy/ day..., that would be 21-30 of the pills you're taking..., i didn't get truly addicted until i started snorting them, which in your case shouldn't be a risk b/c percocet is terrible to snort b/c of the acetaminophen.., if i ware you i'd quit cold turkey or cut the dosage in half for 5 days or so and then quit.., its good that you recognize the problem now b/c this is how things get started, if you don't quit now, two years from now, you could be looking back at this post, wishing you had a 7 pill a day habit, b/c you've moved onto bigger and better (depending on how you look at it) things, such as rs (oxycodon IR without tylenol), h, or dilaudid/opana (hydromorphone/ oxymorphone, respectively)...i know exactly how you feel being ashamed and embarrassed, my family is squeaky clean, and unless some of my relatives are better at hiding a habit than me (i seriously doubt it), i'm the only one with a drug problem, and it is completely humiliating.., i live in fear that my family will find out, b/c i have the kind of family that would def. not understand, but honestly, this can happen to anyone, and no one plans it... three years ago, i would have said no way in hell would i ever do heroin.., but after developing a bad pill habit (again, much worse than yours, so your withdrawals won't be so bad at this point), i was so afraid of the w/d that i have done h a lot..., its still not my drug of choice b/c it honestly still scares me .., but my point is, that no matter how much you think you'll never do something, once the addiction has gotten ahold of you, no one will be more surprised about the things you'll do to feel 'normal,' than you yourself will be.., if you're still feeling high from the drug, you're still at a place where its easier to walk away, simply b/c you don't need it to feel 'normal...,' physiologically, the average person can take up to 20 mgs of oxycodone per day without feeling any withdrawals if they quit cold turkey, luckily you are not TOO far about that right now, so your withdrawals should be pretty mild and not last very long.., but the longer you wait, the worse your habit will get and the withdrawals will become horrifying.., please quit asap, talking to your wife might be a good thing, as she can support you and help you not take a pill every time you feel the urge, its nothing to be ashamed of, as i said, it can happen to anyone, as no one plans to become an addict, everyone i know that does h started with pain pills b/c of an injury, and it doesn't sound like you are to the point of really sneaking behind her back, stealing/ spending savings and doing overall shameful things to feed your habit..., i have a phd and a great job and only started on this horrible path from truly recreational to horrifying habit about two years ago, the same month i was finishing up my phd.., i had a wonderful childhood, have a great education and every opportunity provided to me, so i know first-hand that addiction doesn't discriminate and society's view of addicts as losers is ridiculous, as VERY few people (if any) start out believe that they will be an addict..., i know this is a long, rant-y type answer, but i truly hope that you are able to stop while this addiction is in its early stages..., i would give almost anything to be able to rewind two years of my life and go slap myself silly for messing up my own life and not seeing what was right in front of me when i started snorting pills on a daily basis..., i know right now that prob. seems like something you would 'never do,' but trust me, rehabs are full of people with stable lives and jobs that started on prescribed pain pills and gradually before they knew it were buying h off the streets to feel 'normal,' and 'not sick,' so they could just function...,i've wasted a ton of money and time on drugs and worrying about finding drugs.., when you're an addict it is all consuming and it becomes your new normal.., it sounds to me like you have a wonderful life and family so please, please quit while its a little easier.., i wouldn't suggest subs or benzos or anything b/c those have the potential to just develop into different habits and that isn't your goal...best wishes!!
