I used to eat 2 or 3 (20 mg) pills, wait 20 to 30 minutes, and snort 1 or 2 pills. Rough on the nose, but if you time it right, all the pills will rush you together, it's very cool....but yeah, the crash sucks ass, I've gotten to where I don't do adderall because I regret the whole trip when I'm done.
