m a sophomore in college and took the drug
for studying starting my senior year, then very briefly
for a few occasions after that. But in the last month, for some reason I got cravings for it. I didn't associate the cravings with my needs to cram study time like I had before. But because this last month was setting up for finals, I bought 5 from my friend, took them for some tests, bought another 10, took those for papers, then bought 2 more yesterday.
