"I've been on Concerta since I was about 13 (I'm 22 now).  When I first started the medication I experienced a fair amount of weight loss. Overall, Concerta has truly changed my life and made me a more focused student.  Since I've been on it for so long, I have learned to manage side effects but some that have been ongoing are: upset stomach right after taking the medication (due to the stimulant effects and lack of food), slight headaches, jitters, binging when the medication wears off, and occasional paranoia.  When first beginning the medication, remember to force yourself to have some caloric in-take even if it is just a smoothie.  This has been life-changing, but please remember to balance out your diet."
