I've had some dealings with alcoholics.
When I was younger my mom used to drink and disappear for the prime time hours. Spending money for food and cloths on alcohol. She up-and-down denies it, but the family tells me my father died chocking on his own vomit while drunk on his back.
She still has not giving up drinking. It's cost her a visit to a place best not left to regular non drinkers, and a accident where she flipped a car over. It's also cost her the one guy who would have probably settled down with her.
The second is a friend of mine. His story is long, but the highlights are:
Waking up the wee hours of the morning to drink,
Drinking alone,
Getting so drunk he couldn't remember certain things,
Spending hundreds f dollars each month of beer until it was breaking him,
Buying things that put him in trouble or debt (even almost killing him),
Wife telling him so was going to leave him if he didn't stop,
Hiding empty beer bottle in the trash can, in the tool box, anywhere else,
Passing out (passed out one time whiel standing up, and fell forward, hitting his head into the wall -- he just stood that way),
Doctors telling him if he didn't stop drinking NOW, he was going to die (he kept drinking),
And one time going some place but came back and couldn't remember what he was doing.
Alcoholism, in fact alcohol in general, is a disgusting thing of life. I washed my hands of him and my mother. If someone wants to do themselves in like that, I say have fun -- I'll go on with my life.
For those curious, about a year and-a-half ago he checked himself in to rehab (Which involed driving drunk to another city, by the way). He completely turned his life around, his liver and everything cleared up un beleivably so nicely he's in remarkable health for what happened. He's lost all the weight, healthy, and he got back into the band (which is now owns).
My mom on the other hand...
