Hi @domiha I had exactly the same experience as you. BTW, in my humble opinion, I doubt that 1 or 2 drinks is the cause of your problem. Otherwise, almost everybody would have PN, and/or alcohol wouldn't have been invented.
I used to drink quite a bit; perhaps 3 drinks a day. When I was diagnosed with small fiber PN, I decided to quit entirely. I was "on the wagon" for 3 months, and the PN continued to get worse.
I decided that my experiment wasn't working, but I cut back to one glass of wine/day, when I resumed drinking because of the PN and other reasons.
My logic(?) was that if it wasn't working after 3 months, alcohol probably wasn't the cause, and anyway I enjoy my wine too much to wait years to find out, which I don't have many of left.
I haven't seen a study which adequately addresses this particular question, other than the standard remark that excess alcohol can be a cause of PN. I've also been given completely different answers by my doctors. My guess is that nobody knows for sure.
If you or anyone else has different information, please post.
Thanks and good luck.
