Next day reflections:
I'm still not totally down. When the DXM wore most of the way off, I began to feel what I presume was the pseudoephedrine. I can see how this stuff could give you a heart attack, but luckily I'm a golem so I'm just sort of tense and jittery.
If I were Agent, I'd mention the additive that promises a slow and painful death specifically the next time I recommended this.
I had some difficulty getting an erection. I'm the wrong guy for that to happen to.
I knew a girl who used to trip off cough medicine, but she used coricidin pills. From what I read today, she's fucked up her brain badly.
I'm somewhat surprised that a psychoactive drug which has the potential to be more powerful than acid or mushrooms and is easily more dangerous is just sold over the counter.
