The problem I think is mainly the caffeine. It gives my body tremors, my heart goes too fast & I break out in a sweat. It also doesn't help that there is no AC where I live, & I keep my doors & windows closed all the time so it can get to be almost 90 in my room.

It's just a lot of unpleasant feelings all at once, and if I get hit with something that snags my brain the right (wrong) way I can get stupid.
