I stopped drinking almost 6 years ago. Almost all of the troubles in my past were attributed to alcohol.
My problem was the same as your problem. I had no self control to stop drinking when it was time. Killing almost half gallon a night was easy.
I can tell you countless horror stories Ive had. I have been to jail over 20 times because of alcohol whether it be bar fights or DUI or sometimes things worse than that.
If you know its a problem stop while you are ahead...
