Makes me want to tear my hair out! He was switched from 54mg of Concerta to help him get his work done to 30 mg of Metadate ER. I love that he ate a huge dinner that is definitely a plus, and I am hoping that he will get to sleep before 11 pm or midnight tonight. Those are the two reasons for the switch. The new medicine wears off between 3 and 4 pm. I can see the difference. I like his personality better in the afternoons with the new medication. BUT hardly any homework was done. I guess I will email the teachers.
