From what I've heard from others its very individualistic. Some people have healed quite a bit, others seem to be stuck with the same symptoms but at least halted progression. I'd use the search function and look through past posts. With forum recommended supplements, diet, exercise, and time (lots of time) you may be able to heal a bit and reverse some symptoms. Full recovery seems to be harder to come by, but you have to give your body the right environment for healing. Congrats on sobriety.

I'm only 4 1/2 months into Neuropathy symptoms and am still learning myself. Others may be able to provide a more detailed answer.
