i actually had lots of success with med holidays on adderall i couldnt take too high of a dose though because of side effects palpitations and the meds only last about 6 hours instead of the 8-10 it was supposed to last turns out im a hyper-metabolizer of stimulants we ended up having to switch me to non-stimulants due to the surprise appearance of ist inappropriate sinus tachycardia even medicated for that adderall still shoots my heart rate up to about 130-140 at rest ive still not found my perfect combo of meds using only non-stimulants but my shrink and i are working on it
