It's important to understand how all amphetamines work on the brain. I don't want this to freak you out, but amphetamines are one of the few drugs that actually change brain chemistry in a pseudo permanent capacity.
First off, all stimulants have come downs. That goes for coke, adderall, dexedrine, ritalin, obviously mdma, and even caffeine. These come downs get worse after binges. Adderall is probably the smoothest of all typical amphetamines. That's because its a mixture of L and D amphetamine in 2 different salt forms each. So the rate at which it leaves your body isnt alarmingly quick. But building tolerance to it isnt like building tolerance to other drugs because its not purely receptor based. In other words...theres no amphetamine receptor that gets down regulated with too much use.
Amphetamines work by actually ENTERING your cell and signaling the cell nucleus to release DA, SERT, and NE. The stronger the amphetamine (pure D amphet like dexedrine, methamphete, or just high doses of addy) obviously increases the strength of that release. Then, the amphets also act as allosteric modulators on the transporter proteins outside the cell that are responsible for bringing extra DA, SERT, and NE back for recycling. They reverse this process and make the transporters forcibly remove all those extra neurotransmitters your nucleus pumped out. It effectively causes a 'shredding' of the synapse. In low-moderate doses, this effect is negligible. But a few really strong binges will twack your cells out. That's why you see meth addicts with parkinsons. Even after a meth addict gets clean...their dopaminergic transmission is so F'd up that they develop parkinsons symptoms.
So...I'd suggest avoiding the gnarly comedowns and crashes and lack of a good high but NOT trying to get high...at least for a few months. Also...the neurotransmitters that amphets release come from protein. So if youre not eating enough meats and cheeses...your cells won't have anything to release. And when they do...the synapses are so damaged and your metabolism (bi-product of tolerance) has gotten so good at washing out the amphets that DA, SERT, and NE release no longer happens on a nice, slow, smooth scale but just kinda stops. Then you crash. Let your brain heal for a bit.
