Being sober you will feel more of what is going on in your body. My husband has been sober for several years and the PN is now showing its ugly side and seems to be progressing. Nervers take along time to regenerate, some may never regenerate. Why it is happening to him now? ....well it probably was there all along, but the damage just continued on as the rate of repair cannot kep mup with the damage that was done or ongoing. I hate to think how much worse the PN would be if he was actively drinking! My husband had reached the point where he was about to go on the transplant list, but his liver regained function. We were very lucky.
