Ty2525, welcome. Thank you for your service both abroad and here at home.
Being a police officer is one of the most stressful careers with the highest numbers of alcohol abuse. (Many family members in law enforcement). Have you tried speaking with your union leaders? You will be protected from job loss and rehab or treatment programs are typically paid for. I can assure you, there are other officers in similar positions. Get the help you need now before it gets worse.
You will find plenty of support here. You are not alone.
