Wouldn't your life be better? How much did you spend on alcohol? Imagine you invested this money or started a business with it?
If you never had any alcohol you would have avoided many mistakes, work harder and more easily, you would be smarter, richer, more healthy and with better friends

I just read the question again and realized that you made some stupid arguments; Why would non-drinkers be smarter than drinkers?
And why would non-drinking friends be better friends than the drinking ones?
