Could be a few reasons why but I would suggest getting medical treatment.
alcohol is a histamine hence can cause runny eyes and nose and itching during withdrawal.
could also be low nutrients and a medical professional can issue thiamine or other necessary vitamins if there is a defiency.
im not a doctor just sharing some information I was given and strongly advise seeking medical help as even though it is “normal” still would be best to get any necessary treatment to keep you safe as withdrawals are dangerous.
