Well in my younger days I've certainly been drunk more than twice.
I've only been drunk to the point of not remembering once. Apparently I'm a good card player since I woke up at home with about 12 pounds of change in my pocket. In my defense I was in a safe place with people I knew and had no need to drive or be driven.
The problem with drinking comes when people don't know when they should be stopping or that they are developing a habit.
If you find yourself drinking alone you might want to consider stopping. Though a single drink after work or glass of wine / beer with dinner isn't a red flag.
Surprisingly alcoholics on the road aren't nearly as dangerous as occasional drinkers and the once a year partier is the most dangerous.
But driving or operating machinery while intoxicated is what brings the most grief to our society.
Alcohol is one of the most toxic things we put in our bodies! Its worse than almost any hard drug save meth. Worse than cocaine, worse than heroin, worse than ecstasy it even worse than LSD. But its legal while pot, the least harmful thing we use remains illegal in almost every state and the Federal government.
