I live in the U.S., first off.
I was prescribed a narcotic following a minor surgery. I'm not going to say what kind of surgery that was and please don't ask. I'll just go ahead and say that the prescription was for hydrocodone/acetaminophen 5-35. I'm worried about having been prescribed this because I know there's a state-wide electronic system used to monitor all prescriptions—accessible by all doctors, pharmacies, etc. anywhere else in my state—and I know that system is used to flag people for prescription drug abuse. I also know that medications like this are highly frowned upon by the healthcare system itself and even more so by the authorities. I assume it's entirely possible that I look suspicious according to that system now.
I've only taken a three pills so far, out of ten total. If I take the other seven back to the pharmacy to have them destroyed, they'll make a record of that, I would imagine.
What I mean is that I could just stop taking them now but never tell anyone that, and anyone looking at my medical history in the future would see that I picked up ten pills from the pharmacy, and that's all they would see, and so I took the entire script as far as they know; whereas if I take the other seven back, and they make another entry in their records about that, that's in effect like plus ten and then minus seven, and that way I would theoretically have three pills counted against my medical history instead of ten; right?
I could be way overanalyzing this, but frankly, I'm already terrified to take another one anyway. I honestly don't like how they make me feel, which is good, but it would be just my luck that I'd take one more pill and start liking it immediately. I know what happens to people who end up liking this stuff, and how easy it is to end up liking it; I've seen it. It's also that I'm still relatively young, and my health's already bad enough at this point as it is, that I already know they'll eventually put me in the ground with at least one major surgery, and I don't want to have to get through that with ibuprofen because I've already blown it.
You're overanalyzing their overanalyzing.
