I would suggest you try for a Sober Weekend, doing other activities you enjoy...when Monday comes you'll be fresh and rested to prepare for your classes...make a comparison about how you feel after that as opposed to the anxiety and sick feeling after a 2 day BINGE...
I 'm guessing you are a younger person, please think about taking control before it becomes harder...no one is lying when they say that alcoholism is a PROGRESSIVE disease.
welcome too!
