I read your post several times and am still a little unsure of some places, but I think I got the gist of it.
I take oxycodone 10 mg every four hours while awake and also take fairly high doses of lyrica twice a day and flexeril and lido patches and use a tens unit, heat, etc etc.
I once asked my pain dr if it were possible to stop taking the meds for pain and she said to me that it was possible for anyone, but for me, she was doubtful that I could be successful with that approach, but if I wanted to try, that she would give me all the help she could. I thought that was the nicest thing I could expect from a pain dr.
Right now, I don't want to try that, but I commend you for wanting to try. I don't know what your pancreas diagnosis is, but I had pancreatitis once and I remember that it was very very painful.
In conclusion, I wish you luck and hope you will continue to post and let us know how you are doing and what any of us can do to help you.
I will pray for the success to your endeavor of getting off of the pain medication altogether. If you are not successful however, please be gentle and kind to yourself. This is not an easy thing you are embarking upon. Please do it with a physician's assistance and know that we are here rooting for you.
Believe in yourself. Be kind to fellow humans and animals. Take time to smell the flowers and the coffee.
And by all means, when you are down, ask me for help. I will be there.
