When you drink alcohol..... there is an alternate metabolism in the liver to convert it. It is slower than glucose metabolism, and therefore, when you stop drinking, that is a shock and it takes a while to shift from that process to a different way of handling glucose.

It is explained in this medical video:

about 1/2 thru this video is the liver metabolism explained.

It also reveals why sugar (which is 1/2 fructose) is so damaging.
It is a long video...but well worth it.

So when you stop drinking alcohol, you then crave sweets. This is very common in rehab situations. Increased carbs then need increased thiamine because thiamine is involved in their metabolism. During the first month or so, giving in a bit, will ease the increased perception of PN... but eventually you will have to cut way back on sweets/sugar.

Alcohol is also a blunter of pain and perception. When you don't have it anymore, you feel things more acutely. Alcohol is actually classed pharmacologically as an anesthetic, and was used heavily in the Civil War, for pain, when opium was not available, and earlier in fact all thru history. So I don't think your PN is necessarily worse since you stopped drinking, only more obvious.

You can add in a good Bcomplex. B-right by Jarrow has a long track record here for being sensible and useful, and quality.
It is not expensive and doesn't have too much of any one thing in it to be worrisome, and has the methylated folate now too.
