Well, think back.
Have you ever promised yourself, "I'll have one. Maybe two," and then gone on to have many more than that?
If I could guarantee that I could have one or two, I wouldn't have an alcohol problem. And sometimes, I can/could have one or two. But that isn't how I wanted to drink. I wanted to have three really fast, catch that buzz and then keep it going.
Of course, to keep it going that requires increasing amounts.
Then the buzz starts being an hour long followed by 23 hours of craziness and then later regret.
Then in time the buzz doesn't come any more and I'm drinking to hold off the inevitable shakes and anxiety. Rinse and repeat.
Regardless of what you want to call it, people without an alcohol problem don't drink to drunkenness and if they do, they usually don't do it again for a very long time - if ever.
If alcohol is a problem, quitting is the solution.
