hi EC - and welcome to the forum!
Detoxing from alcohol without medical supervision is downright dangerous.
That's as simple as I can put it.
I had no $$$ for it, either, but went through a State funded clinic to do it.
I didn't check into rehab or anything like that.
But I needed a Doc 'on hand' ... and was able to have that through the clinic.
Check out the sticky on the top of the Alcoholism forums called 'Excerpts from under the Influence' .
there's other sticky's there you might want to read as well.
Good luck to ya, and we're here ... we're just not medical advisors.
