Hi Kimura, I'm no expert but I believe a litre a day of hard liquor is a lot. By your own admission you've try "like 100" times to stop on your own and are unable to. It may be necessary to take a "life time out", and allow professionals to help you. First off, the withdrawal process will be as close to painless as you can get. And then they, along with the good folks at this site, will provide you with some shiny new tools to use that will help keep you away from the booze. But only if you listen and take action (and that is where I have fell short on occasion). But they tell me it works.
