What happened to the old fashioned ways of lighting up a bong to pay more attention in class? Personally it never worked for me but I hear some very good things come from doing it.
Yeh I used to hear that from some people, it's a load of horse shit if you ask me

I only know one person who can study and focus while high and they can do it while sober so it doesn't count.
I'm glad that you asked!
FYI Melchoire, Adderall is simply a racemic mixture of amphetamine salts. (Dextroamphetamine being one of them.) In fact, I always found dextroamphetamine to be much more clean and "user-friendly."
As to how these drugs work? Well, they are AMPHETAMINES! (Like... add a CH3 (methyl group) and you have methamphetamine....) They work predominantly by causing a flood of epinephrine/norepinephrine across the synapses and they also act as a dopamine reuptake inhibitor. [I'm trying to keep this simple.... When you think norepinehprine you should think adrenaline.... "fight or flight mode." When you think dopamine..... dopamine is essentially the neurochemical that is associated with pleasure. Think sex, food, gambling, smoking, etc.... Instantaneous pleasure... So amphetamines act to both flood your body with adrenaline and also to stop your body from "absorbing" the dopamine back up once it has been released...) I hope this answered your question!
As to you, Melchoire; I have an extended history with amphetamine/methamphetamine use for both recreation and studying. I will tell you that there is most certainly a bell shaped response curve. You will see immediate results that are great right away.... Then you will actually see your performance deteriorate well below what it ever started out at. Along with this deterioration your body will also begin to crap out on you. I know that my blood pressure at times was 205/171 pules 220 which undoubtedly will cause long term damage to my heart. (Surprising I'm alive, tbh....) But I can assure you that your health is not what you are going to be concerned with right now.... Because of the immense release of norepinephrine repeatedly, your body will begin to severely reduce the amount that it naturally produces. (The same is true for dopamine... your body will think that it has a new mechanism for supply and thus will not continue to produce/release more.) It's this neurochemical battle that makes methamphetamine HANDS DOWN the most addictive drug ever. Your body will actually become dependent upon amphetamines to initially feel awake, alert, and/or any pleasure at all. Which is okay, presuming you don't factor in your health or any monetary concerns... But eventually, you will actually stop producing those neurochemicals entirely.... So then you are going to be taking amphetamines to TRY to feel close to what you would normally without chemical enhancement. The situation will continue to deteriorate until you are simply unable to derive pleasure from anything at all.
As you know, I have an extensive history with a LOT of drugs. (The popular ones and the designer ones...) Methamphetamine is the only drug that really grabbed me by the balls and almost took my life from me. The only drug that truly made life so miserable, I would have preferred not to live any longer. It starts out fun... but it ends very badly. My A's turned into struggling for D's... My life in shambles. I urge you to leave the amphetamines alone... The worst part about amphetamine addiction is actually caused by the above.... Even once you're clean, your brain has already developed specific neurochemical pathways for these chemicals to be released... Your body associated the amphetamines as the only way to feel pleasure or to feel alive at all. So you feel like a lifeless zombie for a year or two after your last hit.
I promise... it sucks. Badly. Put the shit down while you can.
As to your initial question regarding study aids,
I do take aniracetam on a nearly daily basis for cognitive improvements and it has been a huge success. On top of that, the toxicity is ridiculously low. (p.s. amphetamines are one of the few drugs that are truly neurotoxic as well as cardiotoxic) I have to run right now, but if you have any questions regarding aniracetam, feel free to ask them and I'll respond later when I have more time.
Best of luck, pal.

I knew I could get your attention.

All great information, I appreciate you really taking the time. I still have half of the dex cap left which I plan to take tomorrow and finish my last project.
Are you advising that do not even try adderall? I was gonna get 3 tablets from my friend and use them to study for the finals, I don't plan to make a habit of it. I have 5 finals and only 6 days to study for all of them. I'm normally very bad at staying focused, I get distracted easily etc...I don't have an addictive personality. I had a heroin habit for something like 4 months and I quit that cold turkey.
What do you think? Still not try it?
Dude, wtf. That's not a study aid.
What I know about it, is that it is a CII medication, which means- in the pharmacy we keep it locked up in a safe, in the state of Texas we can only dispense it if it is written on special paper, it has a high risk of dependency, and all the adult patients who use it are the biggest retards on the planet. I love looking at Cody's warning about this medication and then knowing that millions of kids are put on this stuff. I really can't wait for another 10 years or so when all these kids grow up, still addicted to this medication, and try to function in the world. We are in for a ton of HERP DERP.
But I think what makes me the most angry is your friends who are giving it to you are the same people who come to my pharmacy a week early to fill their Adderall saying they're out of medication and they 'don't know why' so it must be because WE shorted them, even though we double count all controls. Then, after wasting half an hour listening to how stupid this patient is, we have to go through the hassle of contacting their fucking doctors who don't even give a fuck to get permission to dispense a controlled substance early, just because little assholes are handing this shit to lazy people. Then after we finally fill the medication we get bitched at because the insurance won't pay for it this early and it's $400 and yadda yadda yadda. You're making my life fucking hard!! 
I would never myself use this, Ritalin, OR Vyvanse, and even if I had a child born with shit-for-brains, I would never let my child be put on any of them.
If it's any consolation my friends get them illegally

Oh and we live in Canada so there's that....
Your stories sound cool...got any more?
