"i&#039;ve been taking ritalin for about 4 months now and it has helped me immensely. i&#039;m a college student and suffer from add, major depressive disorder and ocd. i was put on this during a hospitalization because in the past i was on concerta and it worked wonders. so being on this medication i have been able to concentrate better on my schooling and other tasks. the downfall with this med is that it lasts for about 5 hours before it wears off. the other downfall is that i am recovering from an eating disorder and the loss of appetite makes it hard to want to eat."
