From Bob - Oct-23-2014
I have taken Morphine SR or MS Contin for four years. At times upwards of 240 mg per day. It is expensive in its time release form. I had a very painful lower back problem and morphine seemed to have the least side effects, at first. While it stopped the pain it brought its own curse with it. I managed to loose weight and my back pain is likely much better. Now I am an opiate addict. My Bank cancelled my insurance on my mortgage when I admitted to be on the drug during a routine questionnaire. I slowly began taking more than I originally started with. 60 mg...then 90 mg and so on.
I now take 15 0mg per day and I am slowly determined to end this cursed drug. The trouble I go through to keep a steady supply, even with my doctors full support is a nightmare. Often my doctor is away when I need my Rx filled. Other doctors always believe me to be a junkie. It is very embarrassing. My wife thinks I'm a different person. I left my med bag in a cab while on holidays in Mexico. Could not get more. Ended up in full withdrawal at airport and during flight home. It comes with a whole world of pain that is much worse than my original problem. The pain of full withdrawal is.
20 times worse than my back ever was. This is a one way street. If you are suffering with serious cancer and you need to ease your pain, it is a miracle. Otherwise be prepared for a life changing ordeal.
