I don't know what I wanted the people in here to tell me when I came and said "I can't stop". What were they really going to say? Agreed? No, you can't stop?
Nobody can tell you how to stop except that you have to want to and then you have to physically follow through. You can't do it. Don't buy the alcohol. Don't drive yourself to the store. Don't have it in the house. Don't open the bottle. Don't take the drink. Nobody is forcing you to do this except you and nobody can stop you except you. There is no magic pill. Just don't do it.
It gets easier after the initial week of withdrawal, and I haven't had a craving in a month, personally, but many people report having cravings every. single. day. of their sobriety. Don't expect that you're just going to quit and then not want to have a drink. You may always want to. It will be a willful choice every day, just like putting the drink to your lips was a willful choice you made every day.
