"i am a 3 yr breast cancer survivor and i got severe nerve damage from the waist down from the chemotherapy. i was to the point of taking two 10/500 vicodins up to 3 to 4 times a day.  i am now on 10/650 oxycodone and it&#039;s wonderful! i am a hairdresser and without this drug i could not walk. during chemo i was on the liquid oxy and it works in about 15 minutes. the pills take about 1/2 hour to 45 min.  great drug!"
