Amphetamine / dextroamphetamine
"I learned early in my college career that Adderall allowed me to be more productive during my day without the feeling of full blown crashing. 



I do not struggle with paying attention or ADD/ADHD but I did struggle with extreme laziness/fatigue on a regular basis when I reach college age. Prior to that I never had an issue with motivation or sleepy feeling per say but one day it hit me like a brick and was unable to shake it. Which led me to lying to my doctor about having attention issues to obtain a prescription. 



It also was some what of a antidepressant at the same time. I have never struggled with depression but I did always seem to see the brighter side of things while on the medication."
