Guest 1, sorry coming in a bite late here, but - about alcoholism. (Please read this with a jaunty kind of laughable air okay? I'm worried it might sound 'preachy', I don't mean to.) If you had a particular food intolerance, you wouldn’t eat that food right? Let’s say you gave up wheat 20 years ago and in those 20 years you’ve felt fine. Would you today be saying I’m a wheataholic? Would you consider that a ‘disease’?
Saying you’re an alcoholic is labelling you, like you have some
innate badness inside you. Rubbish! Alcohol doesn’t agree with you, so you don’t drink. It doesn’t make
you bad. It’s the
effect of alcohol that’s bad. How does “
I have alcohol-intolerance” sound? Different?
Labelling you an alcoholic is about as sensible as labelling everyone ‘food dependant’ or ‘cyanide-intolerant’.

Stupid. After 20 years it’s no longer helpful to even think about it being part of what makes you ‘you’.
Do smokers who give up for 20 years call themselves ‘smoke-aholics’ and say they still have a disease? Oh they probably do these days!

It’s just words and labels and they can be so dangerous in shaping how we see ourselves. Sometimes just changing the words slightly can help us see things in a whole new way.
About using terms like ‘practising alcoholic’ (PA). This is how I would describe:
You: someone who discovered they react badly to alcohol and therefore doesn’t drink it. A sensible person!
PA: someone who discovered they react badly to alcohol but prefers to kill themselves quickly by continuing to drink it. Suicidal!
You aren’t in the same category as the PAs. BUT using the terms ‘alcoholic’ and ‘practising alcoholic’ puts you in the same sort of category doesn’t it?

You kind of get the shame rubbing off on you which belongs to a completely separate group of people.
It doesn’t belong to you, it’s not your shame. In fact you have the opposite to shame: you can be really very proud of the fact that you faced your intolerance straight away and dealt with it!
You started out with a lot of hurdles to face (being female, having a brother like yours etc) and in jumping those hurdles, you’re a stronger, wiser person. Tell him that next time he mentions an ‘addictive personality’. “Yeah, I had all those problems and I overcame them, what are your achievements buddy?” Say you have another problem too: ‘idiocy-intolerance’!
Phew. I didn’t realise I felt quite that strongly about this! I think I feel strongly about mis-use of words and giving groups of people labels. We’re all individuals. And you sound pretty cool guest1. P
