"i have been prescribed vicodin 5/500s for over a year due to chronic headaches from a severe sinus problem.  



they work great.  however you have to be careful.  you will build a tolerance over time and need more of them to have the same analgesic effect.



secondly they are habit forming.  if you are on them for a long time and need to use them often, as i have, you will most likely become addicted.  as i have."
