Adderall is an amphetamine mixture, and because amphetamines are a basic (NOT acidic) drug, urine pH influences excretion/elimination. Acidifying the urine (e.g., with Orange Juice or Cranberry Juice) hastens the elimination of Adderall, whereas urinary alkinalization (e.g., with sodium bicarbonate or antacids) extends the half-life of Adderall so it becomes reabsorbed in the bloodstream. The average half-life of amphetamine is ~12 hours, but alkinalizing the urine (making it less acidic and more basic) can increase the half-life up to 30 hours. Every 1-unit increase in urine pH (acid --> base) produces an average 7-hour increase in amphetamine half-life.
Just food for thought...Enjoy! =)
Oh, and to answer your question: I think you can safely take your multivitamin whenver you want. The possible danger here (if there is any) is if you purchase a liter-sized bottle of chewable vitamin C at GNC and carry it around with you as something to snack on every 30 minutes.
