"i&#039;ve been taking it for 7 years and it turned my life around. i am severely dyslexic and have add and am on 30mg to 40mg a day. however, as of recent it has started making me slightly disorientated and even slightly sleepy, and my thoughts come faster than i speak (used to happen before i started taking ritalin with my dyslexia) but it feels worse. i just started interning at an ad company so not the best of times!
