It's a bit nosy really but have found myself wondering about this recently and realised mumsnet wasn't a bad place to ask given how many children of alcoholics there seem to be!
So, I have 2 'official' younger siblings (both sisters) and 2 younger cousins who, for all intensive purposes, are brothers as we were brought up together over many years. I am the eldest of the lot and our age ranges from 28 to 35.
1 sibling is a complete tee total as is her dh. 1 is already an alcoholic. 1 is going down the route towards possibly becoming one but is still fairly far off (more a mental illness issue I reckon). 1 is quite a heavy social drinker, more so than me I think (otherwise, we are quite similar in our attitudes), but not at alcoholic level and I think unlikely to go that way.
I drink when I feel like it, certainly not as much as I drank as a student (when I really hit it hard). I have no problem with drinking, don't think I have an addictive personality and don't drink that much anyway but have noticed that I have more of a problem (too strong a word) with dh drinking a lot of wine (nothing else like beer or spirits) as this is what is mainly abused by the alcoholics in my family.
So how has it worked out in your family ?
