My only advice would be and im not an ex morphine user, my addiction was diamorphine.

As Trav said i had to move away from my so called friends and moved to another city to rid myself of my friends.

Of course the pain is unbearable so you will need pain medication for the first week if morphine withdrawal is like h withdrawal. I use dihydrocodeine for my pain and i hate to admit it but i used benzodiazepines for the anxiety and insomnia. The whole process took around a month before i was totally clean and functioning again. Willpower and help from family and real friends made a huge difference also.

I wiash you the best of luck and hope you can overcome your opiate addiction. It is a nightmare but well worth it in the end.
