I understand that you're going to do what you want, I think a lot of the posts in this thread will also be directed at the hundreds or thousands of people who will read this, looking for experience and hope.
Please keep us posted on your progress, we all are hoping you succeed.
*edit: and for the record, I was drinking as much as you were and I tapered down in three days to zero. Don't drag it out...it's just prolonging your discomfort.
