I'm not sure a glass of wine in the evening will make a difference but I have no medical training or background and it's just my opinion.

If you abstain from alcohol, your neuropathy shouldn't get any worse." -- 6 Causes of Neuropathy — and How to Manage the Condition: https://healthblog.uofmhealth.org/health-management/6-causes-of-neuropathy-and-how-to-manage-condition
