Welcome to SR, Amazon; very glad that you found us.
You have found a very understanding, supportive and encouraging forum.
Read around the forum, giving special attention to the stickies at the top of the Newcomers and Alcoholism forums. There is a wealth of info there.
I hope that you really work hard on finding sobriety and recovery in the next few months. Grad school is an exciting time and such a gift to your future. Alcohol can really mess with that opportunity and your entire life, actually.
Many have found that a Plan for Recovery was instrumental to their success.
I will post a link to a great SR thread on that topic in a moment.
