Howdy. If I could just interject for a minute here....
First, I went through a lot of what you've mentioned and I recently celebrated 15 years of sobriety.
This may sound a bit harsh (and I apologize it if does, but I speak the truth) I think your problem is that you are going about this with "half measures" (as AA would call it). And the most recent example of this is that you say you've been hanging around a message board waiting to hear from someone who is probably very well intentioned, but is still drinking like yourself. What "help" can each of you give the other? Sure, you can trade war stories and talk about your feelings....but that won't get this monkey off your back.
Like you, I saw a lot of myself in Lisa, particularly those scenes where she was shaking as she drank from the bottle. I have been there and I have done that. In fact, my last binge before rehab actually resulted in "broken tolerance", which is this bizarre situation where one's dependency level is actually higher than the tolerance level. In other words, I was in withdrawal, but drinking vodka straight out of the bottle didn't help. It wasn't just scary - it was terrifying beyond words.
I do think you have a pretty good grasp of where you're headed, which is a good start. But if you want the truth, I don't think you're quite scared enough yet. A lot of the things you've tried (and it makes me mad that you've had to go through this, since I believe there are so many whackjobs out there trying to treat this disease!) are simply shortcuts that rarely work.
So I see you in a place where you want to want to get sober. (It reminds me of myself and smoking -- I wish I wanted to quit, because it won't work unless I do. And I don't).
I do think a support group like AA offers you the best chance. But do you see that there's a huge difference between saying on a message board that you "need to get" to an AA meeting and actually getting to one?
During the last stages of my drinking, I started shaking after about 6 hours without a drink. But if you've gone 2 days already, you might not be that dependent yet and therefore not need detox. But what you do need is some form of treatment (possibly outpatient, if you can't get into a center) and a support group like AA.
But nothing will work until you decide you're willing to put sobriety ahead of everything else in your life and you're willing to go to whatever lengths are necessary to achieve it. As they say in AA, recovery is a process, not an event.
I wish I knew the magic words to get someone to that point. I've tried many times. But it has to come from you and you alone. You literally have to wake up one morning and say "enough".
