400 mg of morphine???? The only time I have ever heard of that size dose is with cancer patients to make them comfortable towards the end. On that dosage you are actually dealing with a totally different person with a whole new personality aka drug addict.
See what this doctor thinks about Neurontin for pain management. I was involved in a mining accident that left me with spinal fusion, total reconstruction of my right shoulder and 4 blow discs in my lower back. I had become a drug addict (prescription meds) with taking highly addictive pain medications. Thankfully I finally found a doctor that could help control the pain without the addictive meds.
Rich, you must have been put through pure hell and my hat goes off to you for sticking it out. My best advice is to take care of yourself and see if she can be weaned off all the addictive meds.
