pain
"I've been taking Vicodin or something like it for years. First for migraine headache and occasional back pain. Total of maybe 30 pills a year. 

My most pressing need were bouts with cellulitis. If I were to describe the pain, think placing you leg in a bucket of scalding water up to the knee. I took it round the clock for a few weeks.
 
I now take it for chronic knee and hip pain. The dosage is 5 mg 3 times a day as needed. I rarely ever take 3 doses. Most days maybe 1 or 2 and if the pain is manageable, I don't use it at all. I'm averaging 60 pills every 4 months. 

The talk of addiction precludes me from taking it when I (or even my wife) feel I should. I've never felt high or drugged. The only side effect I see is less pain."
