You can master school/work and not alcoholism because two of those things are able to be mastered, and sadly alcoholism is not.
I'm glad you are okay, but secret drinking is most likely not a behavior you want to be engaging in after the incident 5 weeks ago.
Do you think that would have even happened had you not gotten drunk before hand? The decisions we make while drunk rob us of who we are when we are sober and do not accurately represent who we truly are.
Stick around, read and post. I can say for 100% sure if you go into recovery (abstinence) from alcohol you will eventually no longer feel the need to "master" it, but instead just live your life happily.
