I am so sorry that you are in such a bad place. Back pain can be so debilitating. Perhaps you doctor would consider putting you on Topamax which is used for the treatment of nerve pain. One of the side effects of Topamax is weight loss. Topamax is not a narcotic but a seizure medication. I am presently on Topamax and it is helping me to lose weight that I have gained from being on Lyrica. Ask your doctor about it and he may consider prescribing it for you. No harm in asking and if you are experiencing any leg pain it could help alleviate that as well.
