Quitting

Hello, so I’ve been drinking heavy for like a year and a half(5-6 1.75L bottles a week) and recently tried quitting for a week I was doing 1 shot in the morning and 1 or 2 at night to sleep. Recently I missed my night one and had a seizure but some things I’ve seen say I need to drink close to what I used to but slowly cut it back. I just got tired of it one day is there any other way? I don’t want to die and I can’t really check myself in. Is there anything else I can do?
