Ii take 60 mg of Adderall around 4:45 am daily for what they think is extremely Chronic Fatigue although I'm undergoing tests to see what's really going on. I have been on the same dose for 2 years and now the cardiologist wants me to chart my resting heart rate (I use a monitor and take it when I wake up but don't sit up or get out of bed). Somedays I took the chest strap off at night and didn't put it on and check my HR until about 30 minutes after I took the Adderall. Will Adderall raise my HR if I've been on the same dose for awhile, workout daily, and never increased the dose. I've sometimes taken less but never more once we found a dose that works so I can have energy in the first part of the day.
