"i truly wanted to love vyvanse. i have struggled with securing a stimulant prescription ever since i was diagnosed with inattentive type adhd. i&#039;ve read everything out there on vyvanse and was so excited when my new doctor prescribed it for me. also, i&#039;m so used to waiting for drugs to start working (ssris mainly) that i kept waiting to write this review. what it&#039;s come down to is this: i really just don&#039;t know if vyvanse works for me. i haven&#039;t noticed any significant changes at all. the things i have noticed are small and very possibly coincidental. i am currently taking 20mg, which i know is a relatively low dose, so i tried taking 40mg one day and felt like i wanted to die (nausea, anxiety, etc)."
