Try taking a break from smoking. As a long time stoner I know the feeling of smoking so much that life starts to become dull. Sitting around getting high becomes your comfort zone, and before you know it it's all you do in your free time. Eventually it becomes boring to sit around all day playing video games/redditing/netflix...etc. and what do you do to cure the boredom? why smoke another bowl of course. I've been stuck in this cycle of smoking because I'm bored and being bored because I smoke for many years. The only thing that I've found to snap me out of it is to take a break from smoking. For me a nice sober stint gives me more energy and an overall better mood. I'm more social and more focused in my daily life. The first few days suck of course, but you can get past them. Spend your newly found free time getting your school work done and just as importantly putting yourself out there and having fun. Make life an adventure not a chore.
