Towards the 'end', I did it. I was so incredibly physically and mentally addicted to alcohol, I had to, or I'd go into withdrawal. Makes me physically ill even thinking of those days, luckily it was only a few times.. right before I practically died from alcohol poisoning.
You have lots of good info here. I respect that you honestly thought it was something to treat insomnia. If you couldn't sleep.. would you slam a 6 pack? Or does that seem downright weird and wrong to you?
I would imagine he's driving drunk to work if he's drinking all that liquor and then going to work. I woke up drunk as a skunk many times.. after not having drank for 8 or 9 hours. If you know that he is, you may want to consider contacting authorities before he causes and accident and/or injures someone and you're found liable because you knew he was driving drunk. (negligence). It sucks.. and it's sad.. but it's a choice he's made.
Alcoholism is progressive and ends in death, if left untreated. Period.
