ADHD
"I am 18 but I have been taking vyvanse since I was 16 years old at 70mg and still taking the same dose. It is 100% better than concerta XL it has changed my life 

The appetite is not the worst thing I just get really dehydrated and not notice it I can eat after taking it ( 4h after taking it) 

Keep in mind I have been on stimulant like meds for years now I have grown to fight the appetite effects"
