ADHD
"I&#039;m 14 years old, and I&#039;ve been on Adderall for 4 weeks now and I&#039;ve experienced some side effects.  one of them would be loss of appetite especially in the morning and around lunch.  I&#039;ve already gone from being 117 to 111.  That&#039;s not natural, my friend has the same problem too. I prefer Adderall though because my doctor told me that Vyvanse lasts for 12 hours and if you take it at 12 or 1 on the weekends, then you can&#039;t sleep till 12 or 1 in the morning. Adderall doesn&#039;t cause insomnia if you take it at 12 because it only lasts for 4-8 hours. Adderall really helps me pay attention in school, which is why I&#039;m not failing out of my &quot;College prep school&quot;. Totally recommend Adderall 100%."
