Drug info - 80mg over a day?

[LSDMAN]

SWIM was offered a couple of Adderall 20mg XR, 4 total. Swim opened a capsule and chewed the contents in the morning and took another in the afternoon. SWIM liked the effects and took another 2 capsules in the same form of ingestetion at around 9pm. SWIM knows he will probably not sleep tonight but is wondering if this was too much of a dose for someone who doesnt do meth/amps other than when they are in ecstasy tablets that SWIM consumes.

I felt a cramping in my legs late at night and a friend of SWIM told him he should take some salt and drink more water. SWIM had not been drinking enough fluids.

Other than the cramping SWIM feels great with no other side effects other than jaw clenching.
