Am I having a seizure?

[adashleigh]

I am 23 year old, recently diagnosed with adhd, and i am taking 18mg of Concerta. Lately, in the evenings, when i am reading,or focusing on computer screens, my eyes feel like they are vibrating, and my vision begins to shake. I am making an appointment with my doctor. But it might take time to get in. What is happening?

    I am thinking that it is more the caffeine than the concerta.  And at least one person on the site mentioned below stated he had to cut back on his coffee.
There are lots of good posts on side effects here - http://www.askapatient.com/viewrating.asp?drug=21121&name=CONCERTA
     As always, if this remains a problem do ask your doctor.  Seizures are typically only a problem if one has a prior or family history of them.  But they are nothing to be ignored!  So its certainly worth mentioning this to your doctor.  Best wishes.  Let us know what the doc has to say so others can also learn!

   Are you also drinking coffe or taking any energy drinks before you start to study?
When you say your vision starts to shake - are you seeing flashes of light?  or are things just kind of moving back and forth?
