adhd
"Before taking Vyvanse, I was on Adderall, then Adderall XR for my ADD. Neither were near as helpful for energy or concentration. Vyvanse was able to give me energy and concentration that lasted all day without making me jittery (except the first few weeks I was getting used to it), or wearing off.  

My doctor gave me an attention test to see if I needed Vyvanse. I scored in the lowest percentile. After being on it a couple months, finding my dosage, I took the test again and scored in the top percentile. 

Since then, (seven years later) we've only had to up the dosage once, and that was because I was diagnosed with fibromyalgia, which aggravated all my mental conditions."
