If by 'stimulant medication for ADHD' you mean one of the nootropics like Piracetam then you probably know these supplements crank up metabolic oxygen utilization through the roof. And, common knowledge, oxygen deficits easily trigger migraines. Plus as a byproduct of normal metabolism you pipe out a metric ton of CO2 per annum (according to James Lovelock material) so constantly replenishing the room's O2 level is probably a good idea. Wouldn't want that average 20 pt IQ boost acquired over three weeks to go to waste would we? :-)
