I had an implanted Intrathecal Morphine Pump for approx 17 years (1999-2015) to treat chronic bile duct pain. 
The pump, implanted in my abdomen, delivered a tiny dose of morphine by catheter to my Central Nervous System, into the intrathecal spinal cord area.
I ran out of private funding, my 2nd pump battery died Aug 28, 2015.
I went thru a 2-week acute withdrawal on a tapering dose of a short-acting narcotic.
Having tapered to zero, I remained and remain to this day, in post-acute withdrawal syndrome.
I have to take Kratom, up to $1200/mon to take care of my 91 yo mother and 2 grandchildren, all of whom live with me.
I have no bile duct pain remaining, have eroded disc's in my mid back, but, I can live with the remaining pain from that.
Withdrawal from Kratom is suicidal; physically and psychologically intolerable. I don't use "intolerable" lightly--I literally mean it.
I understand, brain receptor-wise, why I remain in withdrawal from opiates. The opiate receptors in my brain are intractable.
Please help me.
