As everyone seems to be saying... you already know that your life depends on stopping the usage of alcohol. I too would keep after your MD about the medication. From what I have heard from one alcoholic though, your experience was similar. Sadly for him, the terrible aches and all the vomitting still wasn't enough to make him stop which is something I will never understand. The point of the drug however is partly negative reinforcement and I guess if that is all that gets through to you...
I can't pretend to understand your level of physical addiction but I can offer you support if you want it
Godspeed.
