I don't know whether amphetamine induces adrenaline. I have only used it
once in my life. Casually telling my (also student) coworker in a store
I worked part-time to help with bills, early in 1980s, that I had a ton
to study for exams and only one weekend to prepare for them; he turned
to me and smiled and produced something from his pocket. I didn't see
anything in his hands, but when I got closer, there were two tiniest
tiny little yellow colored capsules in his palm. He said take them and
you'll manage.
After speaking about them some more, I agreed to try one of them. Paid
him I think $5 for it.
Next weekend a few hours into studying and becoming more and more aware
that I absolutely didn't have enough time to prepare myself for the two
exams on Monday, my mind went back to that tiny capsule I had. Went and
fetched it and swallowed it with hot tea on top. And waited worried and
in despair, confident that I would blow both exams.
Very soon, the unbelievable mental energy level began to pour in :) I
had not even finished the first chapter till then, but that chapter, and
the following chapters began one by one coming and getting finished and
understood and newer ones coming in. I looked up and it was already
Sunday morning, then I began with the other subject, from the first
chapter, and read and understood them one by one in great ease and
speed. I looked up, and it was Monday morning! I took a nice shower and
drove to school, and in no time took both exams successfully and drove
back home like King. I looked up, and it was Monday evening. Then, for
the lack of anything else to do, I took up my Spanish learning book
which I had never gone beyond the first chapter, and began reading and
learning it chapter by chapter until I realized I have read all 20
chapters! I looked up and it was noontime Tuesday. I went to take a rest
on the sofa at last to think of all this for a moment. Then almost
suddenly after, I woke up and looked up and saw it was morning of an
unknown day. I called the number that gave temperature, date, and time
in Dallas in those years, and found out it was Friday morning!
I tried to figure out what had happened. I remembered the two exams but
could not remember one bit from the material I had learned for them! I
also went over the Spanish teaching book and saw all the chapters only
vaguely sounded familiar, but nothing beyond that. I had forgotten
everything that I had learned.
So that was it. My first and last time. All done by that tiny yellow
capsule, about 2 millimeters long.
