ADHD
"This drug works mildly, not as well as stimulant medications like adderall.   Unfortonately while it mildly boosted concentration and motivation it severely increased my anxiety, ,heart rate, and tremors.   Stimulant medications actually decreased my natural tremors.   My pupils were always dialated as well.  To me this drug is a stimulant like super caffeine not a medicational stimulant."
