"worked great from day one. unfortunately, does not come in a generic form so can be very expensive. my doctor recently switched me to methylin er since it comes in a generic form and is much more affordable.  sometimes i can&#039;t even tell i have taken the methylin er, the performance is so sub-standard to the ritalin la.  i am starting to think a normal life might just be worth the extra $60 a month my insurance doesn&#039;t cover on the ritalin la."
