I am just full of questions this morning. When difficult child started taking Concerta last fall, he said it helped him at school. I noticed recently he hasn't been taking it. At first said he was, but they are not going away. Last time I asked him he said he didn't want to take it because it made him really sad. I questioned this and he said the last two times he took it he had a really bad day. (only takes on school days) I asked if he wanted to try one when he was home, maybe it was just a coincedence. He refused. Is this a side effect? Since it is time released I wouldn't think a need for a booster is necessary is it? He had been doing good. Now with an entire week to make up, he will be playing catch up, and that usually causes issues feeling overwhelmed, lost in some subjects. He does not want to try another.
