"I have mixed feelings on Ritalin I am 16 years old Diagnosed with Aspergers syndrome and ADD. I started taking 20mg in the morning, After about 10 minutes I would start feeling it, i felt full of energy and moderately euphoric. I don't know if this is a "Normal" reaction but it would make me feel almost manic like. But all in all the effects were  helpful! When I would usually just sit on my computer the Ritalin somehow made work enjoyable. I hated math but when on Ritalin and in school it was interesting even fun! it made everything feel positive and perfect. The reason I don't give it a 10 is because it only lasts for 3-4 hours. The comedown from this drug is quite terrible. And it gave me some annoying tics."
