"Let me explain what can go wrong here and what you may want to speak with your Dr about. Focalin XRs effect is much , much, much stronger than Concerta or Ritalin. This is very important to understand, so if you are thinking of switching to Focalin XR from another medication do not go to a similar strength. I was on Concerta 54mg and went to  Focalin XR 40mg. This was a scary experience I got dizzy almost passed out and couldn't tell you what 1 1 was. It was horrible  to say the least. I discontinued the Focalin and tried Adderal. That made me grumpy and sick. I did research and found out about Focalins potency. I am now on Focalin XR 15mg and doing awesome."
