"i am 32 yrs old and have had severe chronic daily migraines/ herniated disc with lots of head and back pain ever since i was 16 yrs old. i also have a tumor on my spinal cord that causes pain as well. i&#039;ve been on every pain medicine that&#039;s out there. my doc switched me to vicoprofen 10mg 4x day due to it not having tylenol in it. i&#039;ve been on it for 2/3 months and it&#039;s working just fine. due to me/my body having a high tolerance level because of taking pain medicines, mostly lortab 10&#039;s for many yrs, the only thing i worry about is building up a tolerance to this as well. i can take on an empty stomach or full. i&#039;m just thankful for the fda coming out with this to help save my liver. hope this helps others!"
