@ektishongram the average person with ADHD is not able to remember to take a medication like atomoxetine often enough to reach the required receptor saturation. amphetamine based medications (adderall, vyvanse, dexedrine, etc) provide nearly double the efficacy on the first dose.
@ektishongram in your situation that is reasonable, however many psychiatrists start those with ADHD on non-stimulants and the medication is discontinued before it ever becomes effective because the human brain requires near FULL receptor saturation for SNRI ADHD meds to relieve symptoms.
