That's a lot of Adderall, you'll be up for over 20 hrs. and no doubt get sick
That guy has no idea what he is talking about. If you take the 3 20mg adderal XR at the exact same time, it could last at the very longest 12 hours. Depending on your tolerance, metabolism, if you ate before taking it, if you drank something acidic before taking it. If the food you at was fatty or healthy. If you eat a full meal, the adderall's effectiveness can weaken up to 44%. On an empty stomach you'll get the full effects. If pills were taken at the same time based on all those factors it could last for 4-12 hours. If you spead the 3 pills apart it can last from 12-34 hours.

What if someone took one 60mg adderall er and the next day they took another one How long is that suppose to be in your urine test?
The half life of Adderall is 10 hours. It takes approximately 55 hours to leave your system completely. The half life of Adderall XR would be even longer. You should give yourself four days, just to be safe.
How many hours does adderall last. adderall tabs?
taking 20mg of adderall will last you four to six hours if you are taking the capsules. dumping the pill strait onto your tongue makes it work faster, but not as long. hope this helped a little...
What lasts longer Generic Adderall or Adderall XR?
Adderall XR lasts longer. The XR stands for extended release and lasts around 8-12 depending on the consumer, mg, & tolerance. Generic Adderall which is actually Adderall IR (Instant Release) only lasts for a few hours (about 4 depending on the mgs) because Adderall XR is made from 2 different "beads" which one type releases automatically n the other type releases in about 4 hours so in the end Adderall xr lasts about 8 - 12 hours. When you pay for the Adderall XR you are paying for the extended release feature. SO Adderall XR lasts longer than Adderall IR.
