I wouldn't worry so much about taking your meds, opiates or no. If you are taking them as they come, and not crushing them in to powder, you don't have much to be so worried over.
these meds are safe if taken as directed, in the form they come in from the pharmacy.
I've been on them for a decade. I don't take them unless I need them. or in greater number then they are perscibed for, and i am not a junkie, or floating about in a great happy cloud.
far far from it. i get no more enjoyment out of my pain meds than I do out of a multi vitamin. But they take the edge off the pain, and I can function, and breathe normally, and good stuff like that.
Don't take all the panic inducing sensationalized junk on the TV news at face value. they want to scare you so you'll watch their show.
in reality, this stuff isn't that addictive. you can become dependant on some, but it's not the same thing as addiction.
and becomeing dependant on a few vicodin? or percocet? unlikely.
relax and just use them as directed when you need to. you'll be fine. worring over a single vicodin is just not worth the stress.
