"i&#039;ve had chronic pain as a result of a coiling embolization in my brain.i was tried on so many different pain meds i thought about throwing in the towel...the cure was worse than the pain at times.thankfully,my doctor suggested methadone.i&#039;ve used this medication for over 5 yrs now with no complications other than having to increase it yearly to accomidate the tolerance effect.i also like it because it is inexpensive and doesn&#039;t leave me feeling high or goofy."
