The best way for me to tell others about what happens to me when I drink is to explain my reaction.
I have explained that I cannot drink because something happens that makes me want to drink more and more once I start.
One woman looked at me like I was crazy when I said that. "Oh, not me", she said. "One is fine."
It was never one for me.
I have a different reaction than other people when it comes to drinking alcohol.
It's an abnormal reaction.
An abnormal reaction is one that differs from what the normal reaction is.
I learned this from listening to Joe and Charlie's Big Book study. They are members of AA, and I am a member of AA.
I hope that you find good ideas here on SR.
