ADHD
"5th month on Vyvanse 30 mg which is on the lower dose end. This med has an awful crash. I exercise 4-6x a week. I eat very healthy. I stay busy. I read so many reviews about the same issue. I did reading about the &quot;minimal&quot; crash felt on this med and it is so scary how pharmaceutical companies try to set the med apart. 
For me it lasts 6 hrs and irritability increases. I think it&#039;s in-part tolerance. Mid afternoon, I get severely irritable, anxious, moody, sleepy, and agitated. It is so uncomfortable, I&#039;m supposed to &quot;up&quot; my dose now...to see it last longer and my &quot;crash&quot; will start later&quot;? "
