"i am amazed at the effectiveness of methadone. i&#039;ve spent the last three years in serious back pain due to a bad disc which ultimately led to back surgery. we tried everything under the sun. i can&#039;t believe how good i feel....no ups and downs, no weird &quot;highs&quot; (which i hated the most about pain medicines) and no more feeling like i&#039;m losing my mind. i&#039;ve never felt so strongly about posting a review before. i am ever grateful to the creators of this pain medicine."
