Sobriety is sipped, not gulped. Tip toeing is a good way to start, don't drink and take it in slowly. Sometimes we have to take it hour by hour.
I threw a glass one time too and I also was not aiming. It hit him square in the forehead right between the eyes and caused a pretty severe gash. I did not intend on hitting him but that is what happened. It left a scar you can see to this day.
I didn't stop drinking. I rationalized and it and justified my actions since it was an accident. I didn't see that any of it was caused by my drinking, I blamed it on his drinking. I was angry that he was out at the bar all evening, never mind that I was home drinking all evening.
You have gotten to the point that you see and once you see, you can't unsee.
Hang in there, take it easy, one day at a time. Everything is going to be okay
