ADHD
"Ritalin made me able to block out everything and focus on reading my boring, tedious nursing books. Take it at least 12 hours before you go to sleep, or else it will keep you up at night with thoughts racing. It suppresses appetite and makes most people lose weight- I actually gained weight because I would be starving and binge eat at the end of the night. I did like Ritalin, but it made me too irritable so I switched to Adderall. That is much more pleasant and even more effective. Focalin 10 mg is good for people with mild ADHD symptoms. "
