I'm a 64 year old woman who had been taking morphine (anywhere from 60-120mg/day) and hydrocodone (up to [3] 5/325/day) for 8 years. In March of 2018 I went through Mayo's Pain Rehabilitation 3-week program. It was the best thing I ever did for my pain! I was able to get off the opiates as well as 2 benzodiazepines (for anxiety) and methylphenidate (an ADD drug). My pain is fairly severe, ranging from a "2" on a very good morning, to an "8/9" on bad days. I now manage my pain through exercise, mindfulness, diaphragmatic breathing, and distraction. Also I still take 1800mg of gabapentin/day.
Recently I tried CBD oil for 10 days and feel that it's marginally helpful in pain reduction. I know that marijuana (THC & CBD) is much more effective for me but alas, medical marijuana is not yet legal in WI.
If I can recommend anything, it would be that you try to be seen at Mayo with the intention of qualifying for their 3-week pain rehab program. They will help you come off the morphine. Actually, I titrated down and off my morphine under the supervision of my pain MD prior to going to Mayo. I did not find it difficult to get off the morphine because I did it slowly under the advisement of my doctor. Even if you don't do Mayo's Pain Rehab program, I would advise you not to stop the morphine on your own. Do it under a doctor's supervision and it will go much smoother!
I was, and still am, amazed that I no longer use any opiates! I do not feel any worse for it, in fact, it has given me my life back! If you can wean yourself off the morphine first, before trying CBD oil, that would be the best course, I think.
