Welcome to HCM.
First of all to much drinking is not good for health.
It might be infectious lymphadenitis
Lymphadenitis is the inflammation and/or enlargement of a lymph node. Most cases represent a response to benign, local, or generalized infections (usually viral). Lymphadenitis may affect a single node or a localized group of nodes (regional adenopathy) and may be unilateral or bilateral.
Hope I have provided the information you needed.
I think you may have some infection in the draining area of the lymphatics. It need to examined for exact diagnosis. I advice you to ENT surgeon for help.
