first time doing adderall, eh? 20-40mgs is plenty enough for a great euphoric 12+hr high, for a first time user...my rule of thumb is DONT go beyond 60mg if ur new to it, as yo may panic and experience negative side effects...if yo have the ADDERALL XR (capsules) with the beads, ur best bet is to dump the beads in a cigarette cellophane wrapper,use the end of a lighter and crsh the beads, dump, use side of lighter and smear the powder good which trns it into instant release adderall, which u will want if ur looking for recreational use, taking them as it is, prolly wont provide much of a kick, just a prolongued very light buzz....always take on an empty stomach to avoid tummy aches....be prepared to lose a nite of meals and sleep, but instense euphoria and mind blowing sex on it. if u decide to take adderall XR as it is, remember if u take, say an adderall XR 30mg, ur only getting 15mg immediately into ur system, and gradually 15mg released 3 hours later. duration of amphetamines is 4-6hrs. new time users sometimes go past 12 hours..me as a chronic user on and off for 10 years, i take 40-60mg a pop and im high for 3 hrs and crash bad, if i have no downers, what i do is to lessen the crash is take a light dose of adderall again to give my body what its cravings=more adderall, so my mood is better, but very little dose to avoid hypertension...thats what i call a speed taper. but new time users rarely experience a crash or comedown or extreme depression, unless you lose sleep, and food, and dose again to feel better, then u may feel shitty. the more u use, the more u will feel worse when adderall wears off. amphetamines are such a magical drug that when taken alot, u lose ALOT OF THE MAGIC EFFECTS it provides=talking for several hours at a time with someone bout the deepest things going back to child hoood, extreme mood lift, just so much i cant explain, treat it like ecstacy and use it sparingly! drink water on adderall to avoid dehydration ( u wont feel thirsty ) but u need to drink water anyway , same with food if it gets ridicolous on binges, vitamins too!! SLEEP IS VERY IMPORTANT, dont expect to re-dose adderall and feel that euphoric blast if u pulled an all nighter, u will just feel an extension of the dulled high.... sleep it key. forgive my rambling
