Just thought I'd add another data point in our quest for the ultimate over-
the-counter hallucinogen -- dextromethorphane, found in Robitussin DM,
Drixoral, etc.
First off, stay away from anything that combines dextromethorphane with
guaifenisin -- guaifenisin, intended to clear your lungs, will give your
horrible diarrhea at the psychoactive dosage level of dextromethorphane.
I used Drixoral Liquid Caps, each of which is supposed to have 30mg of
dextromethorphane, and I took a dose of 150mg, which, according to reports
here on alt.drugs, is half the psychoactive dose of 300mg.
I started feeling the effects of the liquid caps about 30 minutes after taking
them, indicating that the liquid was released faster that I would have thought.
I noticed that I had trouble balancing -- walking caused a little vertigo.
Also, I had a hard time unclenching my jaw, and when I wasn't thinking about it,
my teeth would chatter as if I was cold. I did not notice any hallucinations,
but I did notice some interesting perspective changes. Just when I thought
that I had taken too low a dose for interesting visuals and I decided to go
to bed, as soon as I closed my eyes I noticed that rather than seeing the
normal random patterns of closed eyelids, that out of the darkness were
forming kaleidescopic patterns, interlocking and turning, like patterns on
a turkish prayer rug. If I concentrated on visualizing something, it would
spring into being behind my eyelids in full color -- really very startling.
Dextromethorphane seems to interfere with REM sleep, so that come morning, I was still tired, and I ended up going back to sleep for another 8 hours. I would
say that dextromethorphane, like many hallucinogens, is best used when you have
some free time to recover.
So, that was my experience with 150mg -- let's hear some more experiences
