Methadone
"I was offered 20mg/day of this medication at pain management but was afraid to try it. I had gotten a hold of a few and tried one 10mg pill for extreme fibromyalgia pain because I ran 3 days short on my normal pain meds. 12 hours later and I am still pain free. I'd rather use this once a day than oxycodone 3-4x a day. Mind you, I did extensive research before using the medication. I like the fact that I have been pain free all day without feeling loopy or high. No cravings or discomfort from withdrawing from other pain meds. Would definitely recommend this for anyone with chronic pain or if you just want to detox comfortably."
