How long until it is dangerous?

I have been drinking everyday for 8 months probably at first I would not drink much. But now I’m at 750ml vodka a day – 2 days I try to make it last 2 days. I know this is not 2 long but in the past I abused gapapentin and benzos. I stopped cold turkey a very high stupid dose of benzos and went through pretty bad wd I had to go to er. After that I upped the drinking which I’m now at a bottle a day . I am shakey, sick feeling a lot of dread when I stop Am I at risk of danger? Or should I just try to ween off? In my mind if I can make a bottle last 3 days then 4 days and go from there idk what to do I know I have not been drinking daily for a long time but I do know my gaba receptors are sensetive due to gaba drugs
