How to maximize the effect of adderall.

Do you guys have any tips for getting the most out of your adderall? I have a script for 10 mg tabs, and I usually take 2 or 3 of them on Saturday, Sunday, and Monday. Sometimes I'll take 10 mg on an "off day" if I really need to get some work done.

Any thoughts on this schedule?

How would you avoid tolerance and/or dependence?

Does doing anything differently with your diet make the adderall more effective?
