It's a bit of a dilemma . . . I had 1 parent who was an alcoholic and 1 parent that was teetotal, in the end that marriage predictably ended in divorce, but anyways I ended up having a drink problem and my other sibling became an accomplished "moderate" drinker.
I am now convinced that there's no hard and fast rule to these things, both myself and sibling both had wild teenage years, but then ended up differently in later life, why was this? probably like every disease, some have it and some don't, as mentioned above some may have the necessary genes to lead to an addiction!
Which leads to a disturbing question, on that basis, does example have anything to do with it in the first place, if both my parents were teetotal would I have still become an alcoholic?? . . . food for thought, I doubt i'd probably still be here, chatting to all you guys!!
