saf you sound incredibly brave and determined - good luck!
Lizzie I really identify with a lot of what you're writing, especially this
"I don't know about others, but I have a love-hate relationship with booze. I don't want to romanticise, maybe I need to get over this view, but I've always thought that people who drink a bit too much, like smokers, are often the most interesting ones at the party. Not a boorish drunk, but just people who thrill-seek a little and aren't hidebound by bourgeois and prim stereotypes of 'good behaviour'. I am sure I need to get over this. Fact is, there are lots of things about drinking and getting drunk that are good fun. Problem is, it can stop being fun and the tipping point where this happens creeps up on you without you realising."
I'm still thinking about whether I'd drink alcohol I really don't like the taste of, just to get the effect. And I'm thinking about the 'is alcohol the symptom or the cause' question posed up thread.
I'm thinking that, since I don't think I've spend more than the odd day without some kind of prescription/legal/illegal substance in my system since the age of 14/15, the alcohol is the symptom. I'm incapable of functioning without something to prop me up, pick me up, anaethetise me.
I think that probably answers the first question too - rather than drink cheap crap like white lightning I'd probably go back to smoking dope. That's an effective anaesthetic, ime. Not that I'm planning on that, you understand; just musing on the issue. 
Well, tis 6.30 and I haven't had a drink. DD is home. DP is home and cooking. He looks slightly astonished and said 'are you not drinking again?' and when I said no, he looked slightly stricken and said 'but I was going to have a beer...'
I said that's fine, which it is because I don't like beer so that's not a trigger for me really. The snack earlier made all the difference - I've been thinking about a glass of white in a kind of regretful mouth-watery way but not craving. I know I'll be ok once we've eaten.
I told DP a bit about where I'm at and about this thread. He feels that it's my glugging the white down that's the problem and if I could stop that then my consumption of red isn't a problem. I know a lot of you feel that that is completely missing the point
but it's a good starting point for me.
