How to stop/detox from alc

I’ve been drinking straight vodka the past year and some change I have only 2 months around that period where I was sober, but I can’t control myself it isn’t even for the feeling anymore it’s just to combat the high heart rate and blood pressure that I get when I’m not drunk, I don’t want to go to rehab and I don’t want to go to a hospital, my only symptoms I get when I’m not drunk is the 2 I said and I can’t sleep, I don’t shake or anything and mentally I don’t crave it only physically, I’m currently intoxicated while typing this, I’m just tired of relying on it I’m tired of being tired…. I wanna come on here and ask if anyone went thru the same thing and how to manage the physical symptoms either that be via medications or supplements and dietary changes, I’m 22 6ft male and around 150 ibs im very lean and skinny, I have a abuse problem couple years ago with klonopin, I’ve always had anxiety/panic attacks, anyways I always use nicotine with a 5% salt nic vape which I know is contributing to the cardio effects I’m experiencing, please yall give me some tips I want today to be the last
