I'm gonna conservatively estimate that I have been drunk, legally drunk, about 10,000 days in my life. And that is being conservative mind you.
For the sake of argument let's say I have been waaay drunk 1/4 of those times.
To put things into perspective, I've had more days drunk than you've had on this planet. And I've had more days 'plastered' than you have been drinking.
I am only about 16 months sober. "Ask me the questions bridge keeper. I am not afraid."
If you stop drinking now - FOR ******* GOOD! - I have a pretty good idea that you will enjoy many many years of enjoyment and productivity out of your remaining years.
Think of this. Assuming you live to be 70 and stop drinking now, you will have about as many years sober going forward as I have had drinking in the past.
I am mentally fit and smarter than the average bear.
Think about it.
