tapering from alcohol

So I relapsed about 4 months ago I was sober for 3 months and relapsed it started off with ab a 20cl of vodka I’m now drinking a 70cl of vodka I was also consuming a couple of beers a bottle of tonic wine, coke, weed and I was huffing air duster which I’m definitely not proud of, got of all the drugs nearly a month ago now and I started reducing my alcohol this week I’m now only having a bottle of vodka nothing else, I have severe health anxiety and I’m possibly autistic which I have self medicated with alcohol since I was 18 I believe. I’m going to reduce by 20cl of vodka tomorrow rly not looking forward to it as I know what I’m in for as I quit in January this year, its definitely started taking a toll on my health liver and kidneys hurt, fatigue, cold sweats every night and skin is mega itchy, idk entirely why I’m putting this here I think I just wanted to get it off my chest with like minded alcoholics lol and see how much trouble I’m in for.
