we had this native american cat in my unit in Germany, that was severely alcoholic. He had the shakes all day at work despite sneaking away to sip. He had been getting it sent/snuck in the mail in Afghanistan so he didn't go through withdrawals out there...Then he got caught when we got back, they checked his house and realized how big of a deal it was I guess and they forced him into the barracks (essentially on suicide watch, but unstated). His door had to be open at all times, but his wife was allowed to visit and was sneaking it to him. Dude's trick was to just hide it and drink it in the shower haha. I actually respected the dedication, and he was a good dude just had a serious problem.
Like my dad drinks alot, but not to that level. Apparently his dad was worse, died of liver cirrhosis, but i was like 2 so i didn't remember him at all. You hear stories about severe addiction, and i had seen many a tweaker out here in my youth but i had never seen a full blown alcoholic until then. Gotta admit it changed my opinion on the matter a bit, actually felt a bit of sympathy for once in my life
