Gabriel420, if you are:
1) Staying up for several days straight; and
2) Getting popped for warrants; and
3) Comfortable taking a drug because it "doesn't really start fucking with my heart
hardcore till the 2nd or 3rd consecutive day"; and
4) None of this really bothers you
Then maybe you should
seriously consider where your life is headed Take some shrooms and stay home alone and do some critical self-analysis. If you've never reached a point in your life where you've said to yourself, "I think I'm really starting to fuck up and I better slow down a little" then maybe now is the time. Or just start using meth. Hell, if you're going to fuck around with amphetamine and live like a crackhead, why not do it properly?
I took Adderall/Dexedrine in college for several years. I got it legally from my doctor for ADHD. I was prescribed to take up to 50 mg of Dexedrine (IR - immediate release) a day. I did that a few times when the workload was really high, and I could hardly tolerate the anxiety that that dose produced. Most of the time I took 20 mg in the morning and maybe another 15-20 mg four hours later. This dose didn't make me "high," but it made it so I could sit in the library all afternoon and not mind studying so much (not to say that this is normal or healthy, because Dexedrine let me study harder than a person without ADHD could study). On the days I didn't have to study I didn't take it because it made me feel stressed out if I did. I never put it up my nose.
After a few years, I started to notice that I was getting random chest pains when I took it and even when I didn't. It really freaked me out that this drug I was taking to perform better was probably hurting my heart. So I quit seeing my doctor and I quit taking any kind of stimulant (except for the occasional iced cafe mocha).
My work performance has definitely suffered. It used to be so easy to sit down with a pile of papers and work away for hours without it bothering me. Now it is almost impossible to sit down and complete the boring tasks that I had no problem with while medicated. I don't have the same drive to achieve, nor do I have the self-discipline that the drug gave me, and I don't expect to do as well in my career (less money for less work), but I'm a more balanced person overall and I'm not stressed out.
In short: Amphetamine will make you feel better at first, you can work longer and party harder. Eventually, it will quit working so well, and you will become dependent on it to do the things you did just fine before without it.
