ADHD
"I started on Ritalin for ADHD but I switched to Adderall, because the Ritalin made me extremely irritable. Adderall 20 mg allows me to concentrate, tune out distractions, and manage time efficiently. Negative side effects: suppressed appetite (positive for me!), SOMETIMES slightly irritable mood towards the end of the day, sleeplessness if I take it less than 12 hours before bedtime."
