two days ago I took 35mg total of adderall starting with 15mg at around 7PM then taking two more 5mg's every half hour maybe. Today I took 15 at around 10AM then another 5 every half hour till I reached 35mg. After my last 5 at around 4:20PM I started feeling tingley and my hearts beating fast and breathings a little difficult. The whole story is probably my third time using adderall. Teachers and such thought I may have ADD but I have neve been tested. Just kind of wondering what's going on it feels different then the regular adderall feeling. I weigh 140 and an 5' 11"
