Drug info - adderall tolerance/dependence

[Rise against]

Ok, let me tell you a little about myself. I have ADD really bad, and i have had an adderall prescription for about a year and a half. I take 30mg of adderall xr in the morning and then 20mg after school (btw i am 6'1" and 190lbs). I have never tried drugs (not even ciggerettes) or been high until yesterday, when i accedentally double dosed and took 60mg of adderall. It was amazing, i felt really really really good for about 10 hours. Usually i am really shy, but it made talkative and confident.

I have done some research on adderall/amphetamines and have found out that when abused they form addictions and tolerance very fast. I was wondering, if i take a double dose once or twice a week, would i become addicted?

Also, my resting heart beat was 130 beats per minnute. So, is it bad to excersise while high on adderall, or would i risk heart failure or something? I am in track and i want to take a double dose when i have track meets so i can be more social and make friends (i just moved to a new school).

Any advice and information would be greatly apriciated. PEACE
