"i had a back injury in the marine corp in 1989 i have had 7-9 on the pain scale for over 15 years. i have been on morphine 30mgs 6 times a day, vicodin 10/325 for over six years oxycodone, hydrocodone, fentanyl patches 150 mg every 72 hours, almost any pain medicine you can think of.  i stopped my vicodin cold turkey after six years, if you have been on pain meds you know what withdrawal is and how painful it can be. i went right to gabapentin.  oh my god thank you for this pill it is amazing, absolutely zero withdrawal effects from the vicodin and i was on over 300 mg a day for six years.  i mean it zero withdrawal symptoms. i feel zero back pain and i mean zero. this pill is a miracle i&#039;m on 900 mg 3 times a day."
