Alcohol. Sounds like you need professional help to break your alcohol habit. I don't know what resources are available in the uk but if you found health tap you can look those up. Perhaps a uk medico can suggest where you can get help. Long range like this isn't likely it.
Alcoholic . I am very happy to have you verbalized your inability to quit drinking. This is the first step to sobriety and serenity. Please reach out and find someone to get you into a program to help you stop drinking.
