Hey ChrisExcite, welcome to SR and to a better way of life. Your story sounds a lot like mine. Once I started drinking, I might just have one or two more or I might close the bar down and the afterparty and who knows what I'll remember/regret the next day.
Hope you'll join us in the Class of February 2016 thread here. I've found it's been good for me to communicate with others who are new to sobriety.
