narcolepsy
"I gave Adderall an 8 out of 10 because it is very effective, anyone who is narcoleptic (which is why I use this medicine) will stay awake completely. Depending on the dosage you can stay awake anywhere from 5 hours to even more than 12. The down side to this medicine, and let me be clear that it is just with my experience is that it can make you jittery and excited. It also gave me "false confidence" and just overall made me more outgoing than I usually. Also I found that the first time I used it it gave me quite a high, which I eventually got used to. After several days I started hallucinating things and got paranoid. There are definitely some psychological side effects even more than the ones that I've experienced. "
