Adderall is essentially a weaker version of crystal meth (or vice versa). I have used adderall extensively in college and in affiliate marketing to accomplish various objectives and it has never failed me. Using a prescription of course. Take it from me as I jot down some notes and thoughts on the subject:
-You feel really rewarded for accomplishing tasks and goals. You may have an extreme urge to clean your apartment, finish a school assignment, or finish building a landing page, etc. Mundane and boring tasks instantly become interesting and exciting. It really builds momentum in you, and you never get tired of doing whatever you're doing. This lasts for hours on end and you can do some serious damage towards projects and goals.
-Taking adderall in social situations changes your personality. You're able to drink an insane amount of alcohol without getting drunk, it instantly wakes you up and makes you outgoing and social. You can have sex on adderall for hours on end without coming (whether this is good or bad is up to you). Unfortunately it also gives you "meth mouth," where you will talk non stop about inane/stupid subjects and prevent you from understanding social cues. Especially while drinking, people on adderall are extremely annoying and hyper; they don't know when to shut up.
-Though it does make you lose your appetite, you can still eat on adderall. When I was using it, I would get "high" from cooking elaborate and complicated meals and then eating them.
-Adderall intoxication has 4 stages: the come up, the high, the shoulder, and the tweak. During the come up (approx ~1 hr), you become a productivity monster and sort of feel like you were on ecstasy or cocaine. For the next few hours (3-4), during the high, you no longer feel like you're on harder drugs but still have a huge burst of focus. It's during this time you'll probably think its a good idea to clean your room or change the oil on your car, or some other random chore you've been putting off doing. During the shoulder you're no longer high but still under the effect of the drug, it's kind of building up to the comedown. The comedown is the worst part of the experience, where you literally feel "burned out." You might start having suicidal thoughts, severe depression, as well as agitation. You'll attempt to masturbate, take a shower, eat, sleep, to shake this off, but it will all be futile. An easy fix is to take a sleeping pill and sleep it off, because you'll probably won't be able to sleep naturally for a long time.
-You easily become dependent on it, as I and many others have. It's staggering how much work you can accomplish on even the smallest doses of adderall that in your mind it becomes pointless to go without it. This is the deadliest part of the experience and why I no longer take it, even though my profits suffer. The Pavlovian response is so strong that few people can beat it. I like to think of it like alcohol: probably many of you never go out anymore without drinking, because you enjoy the feeling of being drunk and it makes you more social and outgoing. Similar to alcohol, but for doing work, you'll probably want to be on adderall every time you want to do work or at least larger projects.
On the whole, it really is a wonder drug. Its uses are staggering, and if you do a little research you can discover the fact that it's been swept under the rug, but amphetamines and methamphetamines have been used extensively in America and other countries by all ranges of people. In the military, workforce, and even by housewives or people trying to lose weight, amphetamines have and still are used in large numbers.
Heart problems are not really an issue, though I'm sure it can be a concern for those with heart problems. It substantially raises your heart rate, body temperature, and makes you sweat. Adderall sweat smells a lot worse than regular sweat as well.
Is it worth it? In my opinion, no. The comedown is too hard and it's freakishly easy to get dependent on it. While you won't have cravings for it per se, since it's not physically addicting in my view, you'll come to the sad realization that life is just better on adderall, period.
