The drug holiday is a great idea. You can lose a bit of tolerance, and when you start back, you might be able to trim your dose(if it isn't time release) and save some $$.Shame more of the pills can't be "broken".Folks who pay for their own prescriptions could save some real $$.
With an amphetamine type drug, there is no reason you couldn't adj your dose to the day.Weekend no work-low dose-weekday-lotta brain strain type work-higher dose.If you were cautious and never raised your daily dose over a preset max, you would save $$ and decrease tolerance.When you needed it a lot, it would work better.
