I know it affects everyone differently, but I was prescribed Adderall for ADHD and at 30mg my heartrate was elevated by 25bpm, I didn't feel tired for ~28 hours and I was unable to drive because my brain would get convinced that I was standing still and the road was moving towards me.
I didn't take it a second time, and am now on Focalin.
