lol..
When I come home from work, first thing I do is empty a Heineken.
At diner I drink 2 more. When I'm cooking I allow myself to take an extra one. And when doing dishes I drink one to make up for the boring job.
So that makes 4 on a regular day.
Then in the evening (at dutch coffee time) I take a Jack Daniel's, and right before I go to bed just one more to have a good nights sleep.
In the weekends I don't really count (no point)
And even I am not addicted. So, no, alcohol is not highly addictive, because I could last at least 3 days without a drink if I really had to..
(And it makes me play chess a lot better)

All
really, how do you know?
What's there to know everybody knows that , DRINKS ARE INJURIOUS TO HEALTH
