Welcome to SR. It's good to have you here.
I was a binge drinker, too. I actually didn't even drink every weekend - I probably drank twice a month, maybe three times. When I drank, though, boy did I drink! I didn't think I was an alcoholic... I didn't think I had an addiction... but I knew that SOMETHING wasn't quite right there - I knew somewhere deep down that what I was doing was definitely not normal and was definitely going to get me in deep trouble if I continued doing it long enough. I'll tell you now that I know I am an alcoholic. I know that no matter what, once I have that first drink, I am unable to control myself. I know that I can never drink again, ever, because if I do... well, who knows what will become of me.
I wish you all the best and hope you stick around... it's a great place for support. Good luck.
