So E has been taking Vyvanse for a few weeks. he is taking around 12-15mg every morning. It's hard to tell exactly how much because of the way it's dissolved and measured out. But most days I'm able to get his dosage pretty good and he does well on it. But it wears off after 9 hours and he is CRAZY when it wears off. I don't know if we are noticing it more because he i pretty calm during the day or if it's making him more wild when he's off of it? He like makes crazy noises and bounces off the furniture. He done this before he was on medications but I think not as bad...Has anyone else noticed this with- their kids? we have an appointment with- his pediatrician in a couple of weeks to discuss how he is doing on the medications. So I plan to ask her about it too. But overall they do seem to be helping him.
