Hello, and glad you are in this forum. I know one person personally who has a morphine pump. She has had this for about 8 years. She does just fine. The only complaint is that it sometimes runs out before the home nurse arrives to fill the pump. I have watched this proceedure, and there is nothing to it. She has severe, DDD, DJD, and this device works great for her. I really hope that you get the relief you need. ginnie
