For About 4 Years I Was On 160mgs Twice A Day Of Oxicontin And Oxycodone For Breakthru. I Have Been On Patches, I Had A Pain Pump Inplant With No Relief So They Went Back In To Reposition The Catheter And Ended Up With Spinal Menegitis And Emergency Surgery To Remove Pump And Catheter And They Couldn't Sew Me Up Because They Didn't Want To Trap The Infection. I Was In The Hospital For A Couple Of Weeks And At Home Iv And Visitng Nurse For Ten Days. I Now Take 50mgs Of Methadone With Dilaudid Breakthrough. Sometimes It Helps Some, Sometimes Not Much. I'm Real Tired All The Time But I Also Have Severe Sleep Apnea (not Due To Being Obesed Because I'm Not) Which Flares Up My Fibromyalgia. Cpap Doesn't Work For Me. I Have A Freind With Lupus And She Swears By Kadian (time Release Morphine) And She Said The Methadone Made Her Sleepy All The Time. I Suppose It's Anyones Guess. They Say That Methadone Works Well On Nerve Pain.
