My 6 yr old son just started Kapvay 8 days ago. The first week, he took .1mg at bed time only. We just added the .1mg to the morning and he took a nap this afternoon because he couldn't stay awake. He was falling asleep again before his bed time. When does this go away? Also, what about the emotional ups & downs? When does that go away? Since starting the medication, it seems that the anger has definitely went down but he's still angry... so I guess I'd say that he's angry instead of in an immediate rage. I'm just not sure about keeping him on this medication... he's not himself. :/
