First off, no one is a chicken shit for having a tough time, rough experience, scary experience with spice. Changa is not a "chicken shit's" way out of potentially rough experiences with the spice. I would encourage you to try whatever you think will help, but i would suggest meditation and relaxation exercises prior to using spice.

Yea, I had an experience like that the second time i tried spice.  My first time was beautiful, i died and felt myself join the allness, saw a Taj Mahal and came down swimming in visualizer art. My second time was full of ominous forebodings and discomfort...i thnk i got lost in the colors, i distinctly remember being over there, yet was fully aware that i'd fallen sideways on my couch and curled up into the fetal position.  After that expereince i did not try it again for about two weeks.  I returned to hyperspace after those two weeks and my first thought upon breaking through was, "why the hell was i scared of this?  This is the most beautiful, all encompassing, majestic...anything!".  The spice will do what the spice will do.  It can make for rough voyages at times, but it will always teach you something, even if it is as simple as the joy of rebirth/being alive...

I wish you well on your future voyages and suggest that you do whatever you can to make the most confortable atmosphere possible.
