First, knowing now that you're (only) 19 and have reached the level of talent I've seen in your customs makes me respect (and envy) you even more.
Second, I would echo the sentiment expressed by others here: you can moderate, rather than abstain, if you choose. Sometimes it does take a little time away to realize that, but it's true.
Third, going to college is the beginning, not the end. You will come to learn you have the capacity to handle so much more than you think. Seriously. I beg you to step outside your comfort zone and push yourself (if I could go back in time and kick my lazy college-self in the ass...)
Fourth, whatever you do I wish you all the best, and will miss seeing the work of such a bright light in the customs thread.
Happy trails.
