By the way. Great name! As im a steven!
Im on 30mg of oxycodone/roxicodone - instant release. Lyrica, seroquel xr. Depakote, lamactil, Xanax, diazepam, plus a bunch of heart meds, due to heart failure. Also below.
Come next week im going on methadone. Ive heard great things about methadone from a lot of patients, and a friend who pased away from cancer. also i take valotren gel, soma; mobic. This mix have worked wonders for me.
The methadone will be the typical pain management dose. You can akso try the actiq of fentanyl. It worked for a great friend of mine scotty d. he was hugely opioid tolerant.
He was prescribed a ned called actiq. Its a lollipop you move around ya gums and cheek. Powerful stuff, it helped with my pain. As he gave me two

But at this time in your life for being on opiates for a very long time. I would ask your doctor or pain management dr for that med.
Im also opioid tolerant. So i need to be put on something high dose, just like you. It sucks but a positive attitude some hiw will wirk. Jyst gotta believe in yourself! !!
I brought my pain dr a print out of meds that, is used for pain. And also the prescribing infomation. He was very impressed and said thank you. Cause i did all the leg work.
Im also a chronic insomanic. Ambien, lunesta, and a illegal barbiturate. My psych dr prescribed me Seroquel xr and diazepam. Which worked wonders for me. Sleep and schizophrenia, muscle relaxer.. Low dosages of seroquel worked for my insomnia
So my list is :
Seroquel XR
oxycodone
Lyrica
soma
Mobic
diazepam
xanax aswell (most drs dont prescribe 2 benzos, but he did)
Voltaren gel
Depakote
lamactil
I hope any meds you get works for you. I was bed ridden as well. Add diabetes and neuropathy, plus psychological issues. And you got a good mix.
As always talk to ya doc. Good luck and come back abd tell us what transpired.
