I understand it was dumb but it worked, i didnt get "high" but i just felt extremely focused. I dont have a tolerance at all to vyvance or any other ADHD med, but i have taken it before when prescribed. Around 2 years ago i took a very low dose but stopped it because it didnt do anything. While i was on this dose time went very fast and i got a enormous amount of work done. I am 6 1 135 lbs
