If somebody was to need to take stims (ad 20mg xr or concerta 36mg) to study on finals week 7 days straight, would withdrawl happen upon cessation of use? Also would it be beneficial to take addy on mon, conc on tues and alternate every day so that you're body doesn't become dependent and so tolerance wont increase? Thanks

your body doesn't become dependent on amps, in the phyiscal sense...


you'll crash hard, probably get your appetite back and sleep like a baby..

Naww.
With amphetamines- and especially methylphenidate, you undergo no physical addiction whatsoever.
In terms of mental dependency.. that is really up to your state of mind and how you conceive the drug.
Lets say you suddenly felt that you 'needed' the drug to be that mentally capable; then sure. You'd suffer the hardship of a mental dependence. Then again, if you conceive the drug as a mere study aid, you'll be fine and have no cravings: physical or mental.

*Edit*
Yes you will undoubtably crash like a bitch.
I suggest you purchase some benzos for the inevitably ensuing harsh comedown that one experiences as a repercussion from these types of drug. Especially the methylphenidate- the comedown from this is frequently compared on here to that of meth.
