I once came across a book called 'astrology and alcoholism' by one Ann Parker, though I did not buy it.
It suggested that there is a cluster of personality difficulties, possibly genetic too, that can predispose someone towards alcoholism, including a certain need for stimulation, called the 'alcoholic signature.' Neptune does figure, but the 'blame' is also put at the door of Moon-Uranus aspects, amongst one or two other possible 'culprits.' Jack London's chart was looked at certainly for clues to these alcoholic signatures, possibly Malcolm Lowry's too.
It is probably not in print now, but you never know with Amazon, if anyone is interested...
A very old and good friend of mine is an alcoholic and to be honest, if I were to see the chart, I would not necessarily have gleaned alcoholism from it. Ceres is rising in Leo, Venus opposes the Ascendant, South Node in the 1st is in Leo. Mars and Pluto in hard aspect to Moon also, and yes, her mother does rather sound like the mother than hell and certainly at the very least verbally abusive, to all her children from the sound of it, regardless of Moon positions in each case.
What I do see here is someone who 'has' to be happy at all costs, where it is Christmas every day and that can be such a dangerous route to take, if there is a lot of unhappiness to begin with. I think
Watching this is getting more disturbing, as now I can really see it as a disease process. This friend of mine is not unable to stop drinking, as this can kill, whilst someone recounted to me a tale about a famous Hungarian actor who did die, after stopping altogether - the body couldn't tolerate such a rapid withdrawal. Apparently, the actor in question drank because her parents had totally rejected her and her neediness always drove her partners away. I don't know the birth data in this case, though.
I don't know where there is just a drinking problem to begin with, and where 'alcoholism' begins. My father certainly has had a big problem with drink and sometimes I have thought it is a way of getting in touch with anger and hostile feelings: Libra Midheaven, but an Aries Moon and a Mars-Neptune conjunction square Venus.
The UK is perceived abroad as a nation of alcoholics - certainly in Italy, maybe not so in Hungary, nor I daresay in Poland or Russia, where heavy drinking is also part of the culture. The UK has that Pisces Moon, don't know about these other two countries.
What is disturbing then is that drinking can implicate a whole culture - the UK does seem to keep on having a problem with drinking, and with drugs - first, Victorian Mother's Ruin, now, happy hours and ecstasy, along with all he social problems.
Then too, someone kindly handed me a leaflet from al-anon at a festival here, full of the characteristics of the children of alcoholics. Some of these did not ring true for me at all, whilst others did evince the odd wince...my own Venus square Neptune.
Anyway, that is something else worth considering - the way that for every one alcoholic, there may be at least 4 other people who are being affected by the way that person's drinking.
