Don't they have 50mg time release Adderall?
That's more likely the case. I know people can be prescribed 60mg of Adderall XR, twice daily. But I do believe that's 2 capsules in the morning, then 2 capsules later in the evening (or it's 60mg the entire day, one in the morning one in the evening). I'm not certain which one is it, or if it's both.
Obviously someone with a tolerance would be prescribed that sort of dosage.
Seriously? 120 mg of adderall a day???? I have a mad tolerance and if I took that much id be spun as FUCK
Start with 15-20 mg and add from there.
