It's not as hard as it seems. I'm about to go through the same thing myself for a bout a month for medical reasons. The biggest thing is like the first 24-48hrs, you'll be jonesin...bad. If you're going to chicken out, usually the first 48hrs is when you do. After that, it's cake. Stay busy, excersise, focus on school, enjoy the outdoors. Before you know it, you'll be able to blaze again.

For me, one more toke tonight then I'm on the wagon for a month.
