I have not tried to withdraw from  Morphine since after research I saw the low success rate for detox or just being put onto a different medcation. I have had two bad withdrawal issues due to the pump breaking down and suffereid 3 to 4 days in withdraws until I could get the pump fixed due to the lack of knowledge on how pain pumps work. I live 90 miles from UF and it always breaks on a weekend. 
I am wanting to get off Morphine and all medications for pain in order to be free from the chronic long-term effects of Morphine. And stop always being on a time clock controlled by this medcation. The way our world is going I do not want to be stuck with full-blown withdraws in an SHTF scenario. I understand I will still have pain but will deal with that with non-drug methods.
