I resemble that remark...

Edit: to qualify this a bit more: I'm not saying that the OP's husband's problem is alcohol - although we sometimes underestimate co-morbidity IMHO, a combination of factors that cause or worsen the PN pain. It's just that it's so familiar to me that once you discover alcohol can numb the pain, it is very hard to break that circle. The reward for quitting alcohol in such a case is... more pain.

Initially.

It's important to understand that this pain might go away given enough time for your body to heal on the right supplements, healthy food, and a bit of exercise. This takes time, effort, and some "faith" that it will be worth it, as there are many different types and causes of PN, and not all of them will react to this lifestyle change.
