Welcome to NeuroTalk:

I invite you to visit our PN forum... alcohol comes up fairly often.

This is our B12 thread:

Most testing misses the subtle nerve needs that your have to explore.
1). If you are low in B12 you need attention to this.
Ideally you should get a B12 test to see what your numbers are.
If at 400 or below, you need to supplement this.

2). Another nutrient that helps with alcohol damage is benfotiamine-- a special form of thiamine B1. This is a cofactor in alcohol metabolism and be depleted with abuse.
Here is a benfotiamine post:

It is from a supplement thread which has other suggestions:

Don't expect to understand everything at once. Read it slowly several times over a few days, and then it will be more understandable.

Most alcohol damage can reverse with good nutrition, good food, and abstinence.

You could have LOW blood sugars during the day, and this can cause tingling and numbness. Doctors are rather clueless about this and only a 4 or 5 hr glucose tolerance test will show the LOWs. Lows starve nerves. Typically for diabetes, doctors look to highs out of range, but ignore the lows. Lows indicate insulin resistance and depending on your age, this could be a pre-diabetic state.

So you need to look at things in a slightly different way, and consider some supplements. Read up on the Supplement thread and then ask the questions you need to air.
