I use them occasionally. I am horrible with headaches, they make me not functional. Recently I have had a couple of friends tell me they don't use pain killers at all. When I asked them, they just said they didn't believe in them. (This response usually makes me want to remind them they aren't ghosts, but actual things...)
However, it did pique my interest, and so I thought I would ask.

I have a very high tolerance to pain. After surgeries, I've had doctors/health care providers say they are amazed that I haven't taken anything, as most of their patients, going through the same thing, would have been screaming for drugs!
I was brought up to really look at any pain I have and to find ways to address it without going to take pill. Mom raised strong kids and we are all grateful to her!
I avoid them as I prefer to work on other pain-management options. Sleep (I can make myself fall asleep without using pills), change of position, massage, heat or cold and things like arnica have helped me better than pain drugs.
I am very sensitive to meds (because I so rarely take any). When I have been given them (i.e.: when I awoke to find I was on a morphine drip after my hysterectomy, against my wishes), I am woozy for a couple of days after discontinuing them. I hate that out-of-it feeling.
If I have a headache, I even avoid OTC remedies. More often than not, a big glass of water will help immediately, If that doesn't a nap (even 10 minutes of time relaxing in a dark room) almost always does the trick.
