Hi Roror,
Welcome to the forum. It's hard to tell at this point whether what you are dealing with is alcohol related or not. But, obviously quitting drinking is the best path to take. From the things I've read from those dealing with mild to moderate alcohol induced PN, you can typically get significant recovery once you stop drinking. But, it does take some time.

Might be a good time to do a full review of your lifestyle. Make sure your diet is good, be sure to get some exercise to the extent you can, and stress reduction is always a good thing (but admittedly difficult in today's world)

Taking some supplements may also help. Thiamine (or the more active form - benfotiamine) is a good thing to take if you have alcohol related issues. But, if you look through the forum you will find lots of other information on supplements.

Best of luck with the issues your having - hopefully your feeling better soon
