We just switched off of Focalin XR 40mg because it stops working mid-day. Which means he has to go to the school nurse to have the short acting Focalin administered. We made the switch to Intuniv 1mg and he took his 1st dose last night. Today he is twitchy, cant sit still, it took 4 hours to do two summer worksheets (1 hour at most if he took his time while on the Focalin) and they are almost unreadable. Please tell me that we will see the drug begin to work soon...
