What should i expect when taking 30 mg of adderall (dextroamphetamine and racemic amphetamine) for the first time? side effects?

High dose: 30 mg is a high dose to take for the first time. You may be awake for a long time, be anxious, have elevated blood pressure and heart rate, be able to focus better and complete tasks, have little or no appetite, lose track of time and become super absorbed with an activity, have a headache, and possibly feel twitchy or have muscle tightness i.e. around your mouth.
