Paranoid?

[Boomx2Brian]

Swim was first introduced to adderall in college. He found it was a very helpful study aid. Once even studied for 17 hours straight and it was perfect. Lately though when swim takes it to study it simply doesn't cut it anymore, but Im sure it is because of tolerance. He does not binger as he only takes them for studying purposes only. On average it equals out to approximately 80mgs a month. Lately though, even though dosage has not increased, he gets paranoid. He thinks in his mind about a situation and something going wrong and then he convinces himself that that actually happened. It constantly makes him think to himself. Did I just do this? Did I do that? Is Swin just crazy or is this something many users experience?
