I'm prescribed adderall, and I believe its required by law for docs to ask for EKG (heart test) tests to be done atleast once after you've been on the drug for a bit. I drink coffee, take pre work out supps spaced out between my adderall dosages and I am fine on paper and how I feel.
If you really have a medical condition where adderall will help, appeptite suppression, jitters, insomnia etc. Aren't that common of a side effect. Then again this drug is wayyy over prescribed since pharm companies are corrupt and lobbiest have been paying off politicans to keep revenue high.
